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
Now doing this one I had trouble, the answer I came up with was 1/7x^2
2. Simplyfy without negative exponents
This was my reasoning x^-7+2=x^-5=1/x^5
I guess I got it wrong though?
3. Simplify using positive exponents
I did (-4)(2) (v^7/3+-1/3)= -8v
4. Simplify using positive exponents
I got 3/7x^1/3
Please help ASAP
Can anyone at least help with one?
