5. SQUARE ROOTS AND CUBE ROOTS

 

A. Square Root : If x² = y, we say that the square root of y is x and we write, √y = x.

Thus, √4 = 2, √9 = 3, √196 = 14.

 

B. Cube Root : The cube root of a given number x is the number whose cube is x.

We denote the cube root of x by ³√x.
Thus, ³√8 = ³√2 x 2 x 2 = 2, ³√343 = ³√7 x 7 x 7 = 7 etc.

Note:

(i) √xy = √x * √y
(ii) √(x/y) = √x / √y = (√x / √y) * (√y / √y) = √xy / y
