Question

1. circle each value that is a perfect cube. 27 1,000 90 1 300 72 525 directions: find each cube root.

Explanation:

Step1: Recall perfect - cube definition

A perfect cube is a number that can be written as the cube of an integer.

Step2: Check 27

Since $3^3=3\times3\times3 = 27$, 27 is a perfect cube.

Step3: Check 1000

Since $10^3=10\times10\times10 = 1000$, 1000 is a perfect cube.

Step4: Check 90

There is no integer $n$ such that $n^3 = 90$. So 90 is not a perfect cube.

Step5: Check 1

Since $1^3=1\times1\times1 = 1$, 1 is a perfect cube.

Step6: Check 300

There is no integer $n$ such that $n^3=300$. So 300 is not a perfect cube.

Step7: Check 72

There is no integer $n$ such that $n^3 = 72$. So 72 is not a perfect cube.

Step8: Check 525

There is no integer $n$ such that $n^3=525$. So 525 is not a perfect cube.

Answer:

27, 1000, 1
