What is r, the cube root of 125? r = ____

To find the cube root of 125, we need to determine what number multiplied by itself three times equals 125.

We can write this as:

( r = sqrt[3]{125} )

Since ( 5 times 5 times 5 = 125 ), we find:

( r = 5 )

So, the answer is:

r = 5

This means that 5 is the cube root of 125. If you need more help or further explanations, feel free to ask!
