1. (-5.1)^0
* 1
2. 3g^-2 b^2
* 3b^2/g^2
3. 3/g^-2 h^3
* 3g^2/h^3
4. 2x^-2 y^-2 x=3 y=-2
* 1/18
5. 1/2^-2 x^-3 y^5
* 16
All are correct but the last one is no very detailed
#5 can be either
1
_________________
2^(-2) x^(-3) y^(5)
or
1
______ x^(-3) y^(5)
2^(-2)
If its the 1st equation, it's -3.375
If its the 2nd equation, it's -4.7407
Is the last one -1/32?
can you type out the equation correctly?
as in use appropriate parenthesis
