My answer to the question is as follows:
First one looks like you are squaring the number, then multiplying the result by 4, i.e.
<span>y=4<span>x2
</span></span><span>second one is similar, but instead of squaring and multiplying by 4, you are squaring and then dividing by 2
</span>
I hope my answer has come to your help. God bless and have a nice day ahead!
6x^2 = 54
6(x^2) = 54
6(x^2)/6 = 54/6
x^2 = 9
rt(x^2) = rt(9)
x = 3
hope this helps
