<PRE><B>Question 552258</B>
simplify the square root of (5g)^4.
:
{{{sqrt((5g)^4)}}}
raise both terms to the 4th power
{{{sqrt(5^4*g^4)}}} = {{{sqrt(625*g^4)}}}
;
Factor inside the radical to reveal some perfect squares
{{{sqrt(25*25*g^2*g^2)}}}
:
extract the square root of each perfect square:
5 * 5 * g * g = 25g^2; the greatly simplified version
:
You could probably see this just by looking at it, but perhaps a step-by-step procedure will help you understand what when on here
