Answer 10

i havnt done them

Answer 11

oh ok but for Q1 you are right

Answer 12

For question 2 it is 1/c^-5. To get rid of this negative sign , as in make this power '-5' positive, we need to bring it to the numerator. (note that if this negative power were the numerator you would bring it to the denominator).
So 1/c^-5=1*c^5/1=c^5
Get it?

Answer 13

Anyways for the last question again, like the second question, you want to make the powers positive. So you bring them to the numerator or denominator. And you would get x^3/y^5. Subbstitute in the values of x and y and you should get your answer :D
