posted by .

My friend swears by your site so I thought I'd confirm some of my more difficult answers for my math practice exam. Is the solution set for 8^x = 16^ x+2 is it -2? Next is the solution set for log subscript 5 (2x + 3) = 2 is the answer 7/2? Lastly is the answer to Given: log subscript a 2 = .4, log subscript a 3 = .5, log subscript a 5 = .8 what is the value of log subscript a 60 is the value 1.46? Thanks!

Is the solution set for 8^x = 16^ x+2 is it -2? No.
Next is the solution set for log subscript 5 (2x + 3) = 2
is the answer 7/2

No.

Lastly is the answer to Given: log subscript a 2 = .4, log subscript a 3 = .5, log subscript a 5 = .8 what is the value of log subscript a 60 is the value 1.46? Thanks!
