Oh and btw the x is a variable not a multiplication sign:))
TheSmartOne (thesmartone):
Is it \[(y-4)^{3x^2}\]
OpenStudy (anonymous):
Yes thats what it is @TheSmartOne :))
OpenStudy (acal21):
the problem expanded
x^2y^3−12x^2y^2+48x^2y−64x^2
OpenStudy (anonymous):
What are all those diamond question marks?? @acal21 ,Thats confusing..

\[y ^{3x^2}-4^{3x^2}\]
TheSmartOne (thesmartone):
Wouldn't that be the answer @acal21

@TheSmartOne do you mind explaining your thought process on this? I'm having trouble seeing how this works.

I thought that you could use distributive property
OpenStudy (jziggy):
(a+b)^n =/= a^n + b^n
OpenStudy (jziggy):
From my attempt to expand it:
(y-4)^(3x^2) = ((y-4)^3)^x^2
= [y^3 - 12y^2 +48y - 64]^x^2
which is as far as I think it goes.....
