Can anybody help me with some algebra?
Okay so were reviewing exponents and I'm not very good at them so how without a calculator do you solve the following
2^3.5
2^-3
2^-15
< p>2^30
2^-1.5
None of this is doing my homework for me i just dont understand how to do these w/o a calculator. Thanks so much!
I will rate for any help!

just multiply the 2 by how ever many times it says
2^30 = 2x2x2x2...30 times
hard w/o a calculator
with the negative exponents
you have to make it into a fraction
2^-3 would be 1/8
hope i helped

i think i can help you with this. when you have exponents all you do is multiply each problem by the base (the first number) as many times as the exponent says..
for instance 2^3.5
write it out like 2x2x1(half od two is one)
so the answer would be 4.
sorry if this didnt help. it would help if you write out the numbers.
