When "squaring" a number, it means multiplying a number to itself.
When we square a number x, we multiply x by itselft which is x.
[tex]x\cdot x=x^2[/tex]Ex.
Square the number 4.
x = 4
[tex]x^2=x\cdot x[/tex][tex]x^2=4\cdot4[/tex][tex]x^2=16[/tex]In finding square roots, we just need to find what number must be multiplied to itself in order to get a given value.
Ex. Find the square root of 49.
[tex]x^2=49[/tex][tex]\sqrt[]{x^2}=x[/tex][tex]\sqrt[]{49}=x[/tex][tex]x=7[/tex][tex]n^2=0[/tex][tex]\sqrt[]{n^2}=\sqrt[]{0}[/tex][tex]n=0[/tex]Although, multiplying any number by 0 will give you an answer of 0, since the idea of squaring and square root revolves around the idea of multiplying a number to itself, it must be the same number.
