Learn and apply these rules for taking powers of numbers with exponents,

(x^a)^b = x^(ab) ,

(x^a*y^b)^c = x^(ac) * y^(bc)

and multiplying variables with exponents.

x^a*x^b = x^(a+b)

Here is how this works with two examples. You should do the rest yourself.

(p^2*q)^3 = p^6*q^3

6a(-ab)^7 = 6a*(-1)^7 * a^7 * b^7

= -6a^8 * b^7

The * symbol indicates multiplication, but could be left out
