Question

How do you solve for square and cube roote

Answer 1

The Solution:

To find the square root of a number:

Let A be a number, the square root of A is the a if when a is multiplied by a, the product gives A. That is,

$\begin{gathered} \text{ If }A=a\times a \\ \text{Then} \\ \sqrt[]{A}=\sqrt[]{a\times a}=a \\ \text{ So, the square root of 'A' is 'a'.} \end{gathered}$

Similarly,

Finding the cube root of a number:

Let B be a number, the square root of B is the c if when c is multiplied by itself three times, the product gives B. That is,

$\begin{gathered} \text{ If B=c}\times c\times c \\ \text{Then} \\ \sqrt[3]{B}\text{ =}\sqrt[3]{c\times c\times c}=c \\ \text{ So, the cube root of B is c} \end{gathered}$
