Like the last one, get 5sqrt(x) by itself on one side of the equation, and then square both sides.

janessia Group TitleBest ResponseYou've already chosen the best response.0
and idk where to go from there

divide both sides by 5 :)

janessia Group TitleBest ResponseYou've already chosen the best response.0
but i thought you had to square something or something like that

isolated for sqrt(x) you not there yet div by 5 first

You can do it either way actually. I find it simpler to square both sides at that point so you don't have to deal with fractions. Those fractions would cancel out later anyway, so no need to introduce them in the first place.

janessia Group TitleBest ResponseYou've already chosen the best response.0
how do i do \[(5\sqrt{x})^2\]
 2 years ago

timo86m Group TitleBest ResponseYou've already chosen the best response.0
well (a*b) ^n is a^n*b^n right?

yes so the first is 25 and i still dont kno the second part

x36=25x???

(x−6)^2 is (x6)*(x6) use foil or whatever method you prefer.

Just as an FYI, here's another way to look at squaring a square root: Note that: \[\LARGE (X^{S})^{T} = X^{ST}\] \[\LARGE \sqrt{x} = x^{1/2}\] \[\LARGE (\sqrt{x})^{2} = (x^{1/2})^{2}=x^{(1/2)(2)} = x^{1}\]

ohk thnk u

Wired Group TitleBest ResponseYou've already chosen the best response.1
\[x6=5\sqrt{x}\] \[(x6)^{2}=(5\sqrt{x})^{2}\] \[(x6)(x6)=25x\] \[x(x6)6(x6)=25x\]
