Practice makes perfect

To calculate the value of expression 10 * sqrt(8), we will start by calculating the positive cube root of 8. sqrt(8) We need to think of a number that when multiplied by itself three times results in 8. ?^3= 8 Since 2 raised to the third power is 8, the number we are looking for is 2.

(2)(2)(2)
2^3
8

This means that the cube root of 8 is 2. With this information, we can calculate 10 * sqrt(8).

10 * sqrt(8)
10 * 2
