a^2 x a^5/ a 3 = a^4?
(h^2)^5 = 2 x 5 = h10?
a^7/a^3 = 7-3 = a4?
b^2 c^5 / bc^3 = bc2? or b2c?
first one is right
I don't like your misuse of the equal signs in #2 and #2
(h^2)^5
= h^10
you said (h^2)^5 = 2x5 , which of course is 10, but
(h^2)^5 ≠ 10
should have been:
(h^2)^5 = h^(2x5) = h^10
#3, same thing, and the answer is a^4 , not a4
b^2 c^5/(b c^3)
= b c^2
