\[(a^2b^2)^2=(a^2b^2)(a^2b^2) = a^2a^2b^2b^2 = a^{2+2}b^{2+2}=\boxed{a^4b^4}\]
Shortcut: You can "distribute" exponent like this:
\((a^2b^2)^2 = (a^2)^2(b^2)^2 = a^{2\cdot2}b^{2\cdot2} = \boxed{a^4b^4}\)

oh that makes a lot of sense but will take a while to remember
OpenStudy (anonymous):
(a^3b^2)^3? so i do 3x2? then 3x3 so it would end out as a^6 b^9?
OpenStudy (anonymous):
lol that was easy :)
OpenStudy (anonymous):
wait it said it was wrong

(x^2y^3)^2 ??
OpenStudy (anonymous):
i think i know how to do it i just need help explaining the steps
OpenStudy (aum):
\[\large
(a^m)^n = a^{m*n}
\]
OpenStudy (skullpatrol):
$$\Huge (a^m)^n =a^{m\cdot n}$$
OpenStudy (anonymous):
so then it would be 2x3 which is 6? cause they both equal 6

or does one eqaul 4? i mean like is an answer in the problem a 4? or are they both 6?
OpenStudy (anonymous):
caue im confused about if i multiply 2 and 2
OpenStudy (aum):
\[\large
(a^3b^2)^3 = (a^3 \times b^2)^3 = (a^3)^3 \times (b^2)^3 = ?
\]
OpenStudy (anonymous):
a^9 x b^6 which would be ab^15?
OpenStudy (skullpatrol):
to find the power of a power you multiply the exponents

\[\large a^9b^6\]
But you cannot add 9 and 6 because the bases are different.
OpenStudy (anonymous):
9x6=54 lol
OpenStudy (skullpatrol):
nope
OpenStudy (skullpatrol):
slow down, and think about what you are doing
OpenStudy (anonymous):
well aum said not to add so i multiply right?

OpenStudy (skullpatrol):
what about the base?
OpenStudy (aum):
\[\large
a^9 \times a^6 = a^{9+6} = a^{15} \\ \large
a^9 \times b^6 =a^9b^6 \\ \large
(a^9)^6 = a^{9\times6} = a^{54} \\ \large
\]
OpenStudy (anonymous):
ohhh okay
OpenStudy (anonymous):
@TheSmartOne they keep coming on this question
OpenStudy (anonymous):
@aum i only have x and y so which letter do i use?

@Data_LG2
OpenStudy (aum):
\[\large
(x^2y^3)^2 = (x^2)^2 \times (y^3)^2 = x^4y^6
\]
OpenStudy (anonymous):
so i put that?
OpenStudy (anonymous):
lol i need help
OpenStudy (anonymous):
so its x^4y^6?
