What are roots in algebra?

Answer 1

There are different types of roots, most generally seen is the square root.

it looks like an old school division sign, I will be using ^ to represent it

to find ^x you must find the number that, when multiplied by itself equals x

it is most easily found with a calculator.

A square root can be found by making ^x=x1/2

so ^x=x1/2

When x=9

^9=91/2

^9=3

91/2=3

because 3*3=9 or 32=9

There is also the cube root, which is written as 3^x

this is the same principal as the square root

you must find the number that when multiplied by itself twice equals x

a cube root can be found by making 3^x=x1/3

so 3^x=x1/3

When x=8

3^8=81/3

3^8=2

81/3=2

because 2*2*2=8 or 23=8
