Question

Is H with an exponent of 2, be the same as h x h?

Answer 1

yes! good job! (:
for example:
h = 3
h with an exponent of 2 would be 3 x 3 (:

Answer 2

Yes. This is because if you multiply 2 variables together you can make an exponent available. Also, you could do h to the first power plus h to the first power which would equal h ²
