I am having a difficult problem solving a few algebra problems. I am not new to forums, but am new to this forum. Here is what I need help with.
The first part is all raised to the 3/2.
1.((16a^(-4)) ^3/2 * (4ab^(1/2))^-2
( b^8 )
I got an answer with a denominator. 4
a^8 b^13
According to the rules, is this correct?
2. 4y^(-2) -2x^(-1)
(xy)^(-1)
I am completely lost on this one. Not sure what to do after shifting the variables, to make them positive.
All help will be appreciated.
