Answer:
The answer is 36x^6y^8.
Step-by-step explanation:
First if you see a parenthesis with a power instead of a number, you distribute or multiply it to all the numbers or letters with or without any powers.
(-6x^3y^4)^2 into
-6^2x^6y^8
So now the last step is to use the power if there is a number next to it, like -6^2.
-6^2x^6y^8
36x^6y^8
Now, there you have it! Just remember there may be more steps in other similar problems.
