There is a rule for exponents.
I have added a picture of all the exponent rules, and hope it helps you with the other problems.
The exponent of 2 will multiply with the exponents inside the parenthesis.
So, the exponent 4 will multiply with 2.
4 x 2=8
The exponent 3 will multiply with 2.
3 x 2=6
Final answer
[tex]x^8y^6[/tex]
