Answer:
[tex]\sqrt{b^{2} }=b[/tex]
Step-by-step explanation:
In math the square root of the number x is the number y that when its multiplied by itself the result is x. Like this:
[tex]\sqrt{x}=y\\y*y=x[/tex]
So in this case we would have to find a number that when its multiplied by itself will give us the result [tex]b^{2}[/tex]. This number its [tex]b[/tex] because when we multiply [tex]b[/tex] by itself it gives us the result [tex]b^{2}[/tex].
[tex]\sqrt{b^{2} }=b[/tex]
[tex]b*b=b^{2}[/tex]
