    Question Can someone help me with exponents

    I need help for this problem:

    a^2(ab^3)^2 * b^2(a^2b^2)^2


    and would someone be nice enough to explain how I should solve these problems the next time I encounter them?

    Sorry about the "superscripts", I know how to do those now, thanks to Xavier20.

    Thanks.

    They are all exponents. (^)

    Uhm. Do you mean that those are all multiplications, or were any of those exponents?

    If you want to represent an exponent, use an ^ symbol.

    2^2 = 2x2=4

    Hello,

    I'm not certain if you mean this(?):

    a^2 \cdot (ab^3)^2 \cdot b^2 \cdot (a^2b^2)^2. If so, then expand the brackets first:

    a^2 \cdot (a^2 b^6) \cdot b^2 \cdot (a^4 b^4).

    a^2 \cdot a^2 \cdot b^6 \cdot b^2 \cdot a^4 \cdot b^4. Collect all powers(?) with the same base:

    a^{2+2+4} \cdot b^{6+2+4}=a^{8} \cdot b^{12}
