Thread: Intermediate Algebra Help Please

I'm posting the ones I can't figure out. Help me please.

1) 32a5 + 243 = 0 (that's 32a to the 5th power)

a =

2) a2 - 567 = 0 (that's a squared)

a = or a = (2 answers)

3) 1/7x2=77 (that's 1 over 7 x squared)

x = or x = (2 answers)

Please do not post a large list of questions that you have not even attempted yourself.

As a forum we are here to help you where you get stuck, not to simply do your work for you.

Many of these questions only require elementary algebra knowledge. I would suggest you learn the basics before attempting intermediate.
Any library should contain excellent books on algebra 1.
