Take this intelligent assessment test to evaluate your knowledge of power rules: how to multiply, divide, subtract, add and perform other operations on numbers with powers.

• 1.

### Anything raised to the zero power is...

• A.

1

• B.

0

• C.

3

• D.

2

A. 1
Explanation
When a number is raised to the power of zero, the result is always 1. This is because any number raised to the power of zero is equivalent to multiplying that number by itself zero times, which results in the value of 1. Therefore, anything raised to the power of zero is 1.

### When multiplying two powers that have the same base, you...

• A.

Subtract bases

• B.

Multiply bases

• C.

• D.

Multiply exponents

Explanation
When multiplying two powers that have the same base, you add the exponents. This is because the exponent represents the number of times the base is multiplied by itself. So, when you multiply two powers with the same base, you are essentially multiplying the base by itself multiple times. To find the total exponent, you add the exponents together.

• 3.

### To divide identical bases, you...

• A.

• B.

Power the bases

• C.

• D.

Multiply the exponents

D. Multiply the exponents
Explanation
When dividing identical bases, you multiply the exponents. This is because when you divide two numbers with the same base, the result is the base raised to the difference of the exponents. For example, if you have x^a / x^b, where x is the base, you can rewrite it as x^(a-b). Therefore, to divide identical bases, you need to subtract the exponents, which is equivalent to multiplying the exponents when they have the same base.

Rate this question:

• 4.

### To divide identical bases, you...

• A.

Subtract bases

• B.

• C.

Multiply exponents

• D.

Subtract the exponents

D. Subtract the exponents
Explanation
When dividing identical bases, you subtract the exponents. This is because when you divide two numbers with the same base, the result is equal to the base raised to the difference of the exponents. Therefore, subtracting the exponents gives you the correct result.

Rate this question:

• 5.

### When there are two or more exponents and only one base, you...

• A.

• B.

Multiply the exponents

• C.

Subtract exponents

• D.

B. Multiply the exponents
Explanation
When there are two or more exponents and only one base, you multiply the exponents. This means that you raise the base to the power of the sum of the exponents.

Rate this question:

• 6.

### The derivative of a constant is...

• A.

1

• B.

0

• C.

0.5

• D.

3

B. 0
Explanation
The derivative of a constant is always zero because a constant does not change with respect to any variable. Since the derivative represents the rate of change of a function, and a constant has no change, its derivative is always zero.

• 7.

### A functional relationship between two quantities, where a relative change in one quantity results in a proportional relative change in the other quantity is...

• A.

Power law

• B.

Base law

• C.

Base rule

• D.

Exponent rule

D. Exponent rule
Explanation
The exponent rule refers to a functional relationship between two quantities where a relative change in one quantity leads to a proportional relative change in the other quantity. This means that the relationship between the two quantities can be expressed using an exponent, where the change in one quantity is raised to a certain power to determine the change in the other quantity. The exponent rule helps to quantify the proportional relationship between the two quantities.

Rate this question:

• 8.

### The derivative of the sum/difference of functions is the sum/difference of the derivatives is a proponent of...

• A.

Power law

• B.

Product rule

• C.

Sum/difference rule

• D.

Base rule

C. Sum/difference rule
Explanation
The given statement, "The derivative of the sum/difference of functions is the sum/difference of the derivatives," aligns with the sum/difference rule of differentiation. This rule states that the derivative of the sum or difference of two functions is equal to the sum or difference of their individual derivatives. Therefore, the correct answer is the sum/difference rule.

Rate this question:

• 9.

### A method of finding the derivative of a function that is the ratio of two differentiable functions is the...

• A.

Power rule

• B.

Power base

• C.

Base power

• D.

Quotient rule

D. Quotient rule
Explanation
The quotient rule is used to find the derivative of a function that is the ratio of two differentiable functions. It states that the derivative of the quotient of two functions is equal to the numerator's derivative times the denominator minus the denominator's derivative times the numerator, all divided by the square of the denominator. This rule is essential in calculus when dealing with functions that involve division, allowing us to find the rate of change of such functions.

Rate this question:

• 10.

### A character that is set slightly above the normal line of type is...

• A.

Figure

• B.

Number

• C.

Character

• D.

Superscript

D. Superscript
Explanation
A character that is set slightly above the normal line of type is referred to as a superscript. Superscripts are commonly used in mathematical equations, scientific notations, and footnotes to indicate exponents, references, or smaller characters. By positioning the character higher than the baseline, it appears smaller and slightly elevated, making it easier to distinguish from the rest of the text.
