    When you have an exponent to a power, you multiply the exponents: \[(x ^{5})^{2}= x ^{10}\] And in your example, you're right!

    you have to raise everything to the power of 4, not just the \(q^2\) part

    your answer shows the power of 4 operating on q given your answer... the question would have been 3(q^2)^4

    \((ab)^n=a^nb^n\) so \((3q^2)^4=3^4q^8\)

    \(3^4\neq 3\times 4\) \[3^3=3\times 3\times 3\times 3\]
