Simplify
- 32ab^5
- 32a^2b^6
- 32a^2b^5
- 12a^2b^6
Correct Answer

A. 32a^2b^6

Explanation

The given expression is 32ab^5. In order to simplify this expression, we can combine the coefficients and the variables. The coefficient is 32, and the variables are a and b. Since there is no other expression to combine with, the coefficient and variables remain the same. Therefore, the simplified expression is 32ab^5.

Simplify
- 4x^3/y
- 4x/y
- X^3y/4
- 4y/x^3
Correct Answer

A. 4x^3/y

Explanation

The given expression is 4x^3/y. To simplify this expression, we can divide the numerator and denominator by 4. This gives us x^3/y, which is the same as x^3y/4. Therefore, the correct answer is 4x^3/y.

- -9x^6y^3
- 9x^5y^2
- 9x^6y^2
- -9x^5y^2
Correct Answer

A. 9x^6y^2

Explanation

The given expression is -9x^6y^3. To simplify this expression, we can divide both the coefficients (-9) and the variables (x and y) by their common factors. Since the variables have exponents, we can subtract the exponents when dividing. Therefore, the simplified expression is 9x^6y^2.

Write in scientific notation: 0.000742
- 7.42 x 10^-4
- 7.42 x 10^4
- 0.742 x 10^-3
- 0.742 x 10^3
Correct Answer

A. 7.42 x 10^-4

Explanation

The correct answer is 7.42 x 10^-4. This is because when we write a number in scientific notation, we express it as a decimal number between 1 and 10, multiplied by a power of 10. In this case, the decimal number is 7.42, and the power of 10 is -4. This means that we move the decimal point 4 places to the left to get the original number, which is 0.000742.

Simplify .
- -10x^3 - 4x^2 - 3
- 6X^6 - 4X^4 + 6
- 6X^3 + 4X^2 - 3
- -6x^3 - 4x^2 + 3
Correct Answer

A. -6x^3 - 4x^2 + 3

Explanation

The given expression is a polynomial. To simplify it, we need to combine like terms. In this case, we have terms with the same variable and exponent.

Starting with the x^3 terms, we have -10x^3 and -6x^3. When we combine these, we get -16x^3.

Moving on to the x^2 terms, we have -4x^2 and -4x^2. Combining these, we get -8x^2.

Finally, we have the constant terms -3 and 3. These cancel each other out.

Putting it all together, we get -16x^3 - 8x^2. Therefore, the correct simplified form is -16x^3 - 8x^2.

- 9x^3 - 5x^2 + x - 16
- X^3 - 25x^2 - 11x - 16
- 9x^3 + 25x^2 - x + 10
- X^3 + 5x^2 + 11x - 10
Correct Answer

A. 9x^3 - 5x^2 + x - 16

Explanation

The given expression is 9x^3 - 5x^2 + x - 16. This expression cannot be simplified further since it is already in its simplest form.

Simplify
- 6x^2 + 7x - 2
- 5x^2 - x - 3
- 6x^2 + x - 2
- 6x^2 + x + 2
Correct Answer

A. 6x^2 + x - 2

Explanation

The given expression is a fraction with a numerator of 6x^2 + 7x - 2 and a denominator of 5x^2 - x - 3. To simplify this expression, we need to factor both the numerator and the denominator. The numerator can be factored as (3x - 1)(2x + 2), and the denominator can be factored as (5x + 3)(x - 1). By canceling out the common factors of (3x - 1) and (x - 1), we are left with the simplified expression of (2x + 2)/(5x + 3). However, this does not match any of the given answer choices, so the correct answer is not provided.

- 9x^2 + 4
- 9x^2 - 12x + 4
- 9x^2 - 4
- 9x^2 + 12x - 4
Correct Answer

A. 9x^2 - 12x + 4

Explanation

The given expression is a quadratic expression in the form of 9x^2 - 12x + 4. To simplify the expression, we can combine like terms. Since there are no like terms in the given expression, we cannot further simplify it. Therefore, the correct answer is 9x^2 - 12x + 4.
