    You want to get x alone on one side. How can you do that? :)

    i can do that by subtracting i think @Babynini

    hm no because x is not added to 44. it's multiplied.

    it's ok! me too lol. So since it's multiplied, we're going to divide.

    divide both sides by 44 x=432/44

    (we got rid of the 44 on the left side by dividing it by 44!)

    so you just simplified the right side. and now your equation looks like this x=9.8 that's your answer :) (Do they ask for it in decimal or fraction form?)

    If (4^4)x = 4^32, what is the value of x? im very sorry i wrote the equation wrong.

    because it's 4, 4 times. so what does 4 * 4* 4*4 = ?

    ok, let me try to explain this better sweetie. \[4^4= 4x4x4x4\] so first we take 4x4 = 16 then we take that answer and multiply it by 4 16x4 = 64 then we still have to multiply it by 4 one more time because we've only done it 3 times. 64 x 4 = ?

    perfect, and that's your answer for 4^4 because now you've multiplied 4 four times. make sense?

    (4^4)x = 4^32 now we have 256x=4^32

    let's try getting x on one side by itself first then actually. so (4^4)x=4^32 we just did this, how do we get x by itself?
