not sure about this last one ... you really need to use some grouping symbols so one can understand your syntax.
The first question is
1. Simplify without negative exponents
-7x^-2
Now doing this one I had trouble, the answer I came up with was 1/7x^2
2. Simplyfy without negative exponents
x^-7/x^2
This was my reasoning x^-7+2=x^-5=1/x^5
I guess I got it wrong though?
3. Simplify using positive exponents
(-4v^7/3)(2v^-1/3)
I did (-4)(2) (v^7/3+-1/3)= -8v
4. Simplify using positive exponents
3x^2/3/7x
I got 3/7x^1/3
Please help ASAP
Can anyone at least help with one?
