Which expression is equivalent to ((2a^-3b^4)^2(2a^5b)^-2)^-1?
tresset_1 [31]

Using the rules of exponents

\left(a^{b}\right)^{c}=a^{(b\cdot c)}\\a^{b}\cdot a^{c}=a^{(b+c)}

you can simplify this to

\left(2^{(2-2)}a^{(-3\cdot 2+5\cdot (-2))}b^{(4\cdot 2+1\cdot (-2))}\right)^-1\\\\=\left(2^{0}a^{-16}b^{6}\right)^{-1}\\\\=\dfrac{a^{16}}{b^{6}}

None of these answer choices matches the given expression.
