Multipy out the constants and add (or subtract) the exponents of x and y that appear more than once.
Note that (3xy^2)^2 becomes 9x^2 y^4
Exponents in the denominator get subtracted.
If you don't try this yourself, you will continue to have difficulty with the subject.
perform the indicated operation and give the answer in simplified form.
6x^2y^3(3xy^2)^2
