How does exponents work? Is it ust multiplication...please help me i am in grade 7 math

It is multiplication and more.
For instance, a^2 is a times a
a^3 is a times a times a, or a cubed.
Now it gets a little more fun.
a^(1/2) is the sqrt(a)
a^(1/3) is the cubrt(a)
a^(4/3) is the cubrt of a^4
neat. 
like 2>2 is 4 and 2>3 is 8 because the first time you multiply you multiply by the original number???am i right ...sorry if its confusing???

You're right.
But be sure you use the correct signs.
2^2 = 4
2^3 = 8 
thank you Ms.Sue and BobPursley

You're welcome.
