How much do you know about exponents, scientific notation, and cube roots? Exponents are numbers that you repeatedly multiply by the number in the exponent. Scientific notation is a way of expressing too large or too small numbers to be written in decimal form. A cube root is a value which when multiplied by itself three times, produces the original See morevalue. You absolutely must take this impeccable quiz.

Write the number is scientific notation 0.00098
-
98.0 x 10 ^ 5
-
9.8 x 10 ^ 4
-
9.8 x 10 ^ -4
Correct Answer
A. 9.8 x 10 ^ -4Explanation
The given number, 0.00098, can be written in scientific notation as 9.8 x 10^-4. This is because when we move the decimal point 4 places to the right, we get 9.8. The negative exponent of -4 indicates that the decimal point has been moved to the left, making the number smaller.Rate this question:

Write the number is scientific notation 1,420,000
-
1.42 x 10 ^ 6
-
14.2 x 10 ^ 5
-
0.142 x 10 ^ 7
Correct Answer
A. 1.42 x 10 ^ 6Explanation
The number 1,420,000 can be expressed in scientific notation as 1.42 x 10^6. In scientific notation, the number is written as a decimal between 1 and 10 (in this case, 1.42) multiplied by a power of 10 (in this case, 10^6). This notation is used to represent very large or very small numbers in a more concise and standardized format.Rate this question:

0.00534
-
0.000534
-
53,400
Correct Answer
A. 0.000534Explanation
The given number, 5.34 x 10^-4, is written in scientific notation. In standard form, we move the decimal point 4 places to the left because the exponent is negative. Therefore, the correct answer is 0.000534.Rate this question:

Correct Answer
A. 32,501,000Explanation
The correct answer is 32,501,000 because it is the only option that matches the given number, 3.2501 x 10^7, when written in standard form. The other options either have additional decimal places or do not have the correct number of digits.Rate this question:

Which choice represents the expression below as a single exponential expression? 99 * 97
-
9^16 * 9 ^16
-
9^63
-
9^2
-
9^16
Correct Answer
A. 9^16Explanation
The expression 99 * 97 can be written as 9^2 * 9^16. When multiplying two numbers with the same base, the exponents can be added together. Therefore, 9^2 * 9^16 simplifies to 9^18. However, none of the answer choices represent 9^18. The closest answer choice is 9^16, which is the correct answer.Rate this question:

Which choice represents the simplified exponential expression? ((-11)-3)7
-
(-11)^ -10
-
(-11)^ -21
-
-11
-
(-11)^4
Correct Answer
A. (-11)^ -21Explanation
The correct answer is (-11)^ -21. This is the simplified exponential expression because it represents raising -11 to the power of -21. The negative exponent indicates that the base (-11) should be inverted, and the positive exponent indicates how many times it should be multiplied. Therefore, (-11)^ -21 represents dividing 1 by (-11) 21 times.Rate this question:

If the answer is 5 what is the cube root ?
-
120
-
25
-
125
-
100
Correct Answer
A. 125Explanation
The cube root of 125 is 5 because when you multiply 5 by itself three times (5 x 5 x 5), you get 125. The cube root is the number that, when multiplied by itself three times, gives the original number. Therefore, 5 is the cube root of 125.Rate this question:

The cube root of 216 is 6. true or false?
-
True
-
False
Correct Answer
A. TrueExplanation
The cube root of a number is a value that, when multiplied by itself three times, gives the original number. In this case, if we multiply 6 by itself three times (6 x 6 x 6), we get 216. Therefore, the statement that the cube root of 216 is 6 is true.Rate this question:

If the volume of a cube is 64 inches. What is the length of edges?
-
16
-
4
-
21.3
Correct Answer
A. 4Explanation
The volume of a cube is calculated by multiplying the length of its edges three times. In this case, the volume is given as 64 inches, so we need to find the length of the edges. By taking the cube root of 64, we get 4. Therefore, the length of the edges of the cube is 4 inches.Rate this question:

If the volume of a cube is 512 feet. What is the length of its edges?
-
8 feet
-
128 feet
-
246 feet
Correct Answer
A. 8 feetExplanation
The volume of a cube is calculated by multiplying the length of one of its edges by itself three times. In this case, the volume is given as 512 feet. To find the length of the edges, we need to find the cube root of the volume. The cube root of 512 is 8, so the length of each edge of the cube is 8 feet.Rate this question:

Correct Answer
A. 5.4 × 10^3, 4.5 × 10^4, 5.4 × 10^4Explanation
The correct answer is 5.4 × 10^3, 4.5 × 10^4, 5.4 × 10^4. The numbers are arranged in order from least to greatest by comparing the coefficients (5.4 and 4.5) first. Since 4.5 is smaller than 5.4, it comes before 5.4 in the list. Then, we compare the exponents (10^3 and 10^4). 10^3 is smaller than 10^4, so it comes before 10^4 in the list. Therefore, the correct order is 5.4 × 10^3, 4.5 × 10^4, 5.4 × 10^4.Rate this question:
