How do you work out what (5a) [to the power of 5] / (5a) [to the power of 3]? I need help!

[From: ] [author: ] [Date: 13-05-04] [Hit: ]
= 5a 5-3 and do I include the brackets?If the base is the same for both,......
Can someone show me how you solve this?

(5a) *to the power of 5*, divided by (5a) *to the power of 3*

Since 5a is the common base, do I subtract the powers together? like,
= 5a 5-3 and do I include the brackets?

-
(5a)^5 / (5a)^3

If the base is the same for both, all you have to do is subtract the exponents
5-3 = 2
so the answer is
(5a)^2 or 25a^2
