Question

How can we find root of any number? ​

Answer 1

We can find root of any number by long division method

Answer 2

actually root of any number is having power as a fraction.

for ex:-

√4

$\sqrt{4 } = {4}^{1 \div 2} = { {(2}^{2} )}^{1 \div 2} = {2}^{2 \times 1 \div 2} = {2}^{1} = 2$

similar if it is

$\sqrt[3]{x} = {x}^{1 \div 3} \\ \sqrt[4]{x} = {x}^{1 \div 4}$

$so \: \: \sqrt[y]{x} = {x}^{1 \div y}$

This is one way of finding root of any number.
this is for perfect square numbers .
but for non perfect square numbers you have to use long division method.

hope it helps you.
