log5x+log5(x+5)=6 There are two potential roots, A and B, where A≤B. A= B= Is A actually a root? (yes/no) Is B actually a root? (yes/no)

Anyone?? help, please!

Show your solution.

ln(3t + 2) = ln 4 + ln(t − 2)

log3(x + 4) = 1 − log3(x + 2)

log x + log(x + 30) = 3

16^3x + 2 = 1/32

logx 2 = 1/2
