Answer 1

@TheSmartOne I see you're helping someone else, don't rush. Just come whenever you can, I can wait. I have all day today :)

Answer 2

please check the question once again.

Answer 3

okay let me see what i can do here

Answer 4

nvm the smart one got it :P

Answer 5

Is the question supposed to be

\(\Large\frac{(12^{-5})^2}{12^{-4}} = 12^x\)

Is that all equal to 12^x?

Answer 6

Yes, the X is the missing exponent.

Answer 7

You need to use this property first:

\(\Large (a^b)^c = a^{bc}\)

and then you use this property

\(\Large \frac{x^y}{x^z} = x^{y-z}\)

Answer 8

Ok so, sorry. I'm really confused. So would I add the exponents together or no?

Answer 9

no, you multiply the exponents in the numerator

Answer 10

So I do 12 x 5? Or do 12 x 12 x 12 x 12 x 12?

Answer 11

\(\Large (a^b)^c = a^{bc}\)

\(\Large (12^{-5})^2 = 12^{??}\)
