    In all these expressions you have a power of a power.

    You can solve them simply multiplying the exponents.

    Remember that any quantity raised to the zero is equal to 1.

    .

    11) (n^4) ^8 = n^ (4*8) = n^32

    13) (q^10) ^10 = q^ (10*10) = q^100

    15) (x^3) ^-5 = x^[3 * (-5) ] = x^ (-15)

    17) (z^8) ^0z^5 = z^ (8*0) z^5 = z^0 z^5 = 1*z^5 = z^5

    19) (c^3) ^5 (d^3) ^0 = c^ (3 * 5) d^ (3*0) = c^15 d^0 = c^15*1 = c^15
