Answer 1

The square root of 121 is 11

The square root of 900 is 30

The cube root of 125 is 5

The cube root of 729 is 9

Answer 2

√121 = 11

√900 = 30

∛125 = 5

∛729 = 9

Explanation:

we have to find the values of √121,√900, ∛125 and ∛729

√121 =√(11×11)=11

√900 =√(30×30)=30

∛125 =∛(5×5×5)=5

∛729 =∛(9×9×9)=9

Hence,

√121 = 11

√900 = 30

∛125 = 5

∛729 = 9
