Question

Someone please help! Will medal!
(3z?)3 = 27z18
? represents an exponent, but I don't know which one it is. Since 3 to the third power is 27, I thought it would be three. But, 3 * 3 only equals 9 and 3 + 3 = 6, I'm confused.

Answer 1

are you sure that's your problem? That it's \[(3z^{x})3 = 27z18\]?

Answer 2

Yeah, the paper says it. I only follow what was written. :/

Answer 3

ok so it looks exactly like I have written it right?

Answer 4

Yeah.

Answer 5

ok then what you must do is solve for x. Do you know how to do so>

Answer 6

Not exactly. :/ I know I'm supposed to multiply the (missing) power by the coefficient, then multiply the powers and add it to the variable. Er, at least that's what I learned.

Answer 7

hmmm honestly it sounds like you wrote the problem wrong. But I will help you solve this problem regardless. So first just move every you can to the other side of x.

Answer 8

Okay, wait. I know the answer is 6 now, but I just have no idea how to get there.

Answer 9

well if the answer is 6. The problem certainly is not what I posted

Answer 10

I don't know anymore. I'll just go in to class with what I have, thanks anyway!

Answer 11

ok no problem
