A few trig problems help please

4th radical of (a^2/b) ... how would you use logs to solve it?

(2+ √3)/(2-√3) ... what is it equivalent to?

log4 + logx =28 ... find x.

Please include explanations. Thanks in advance!!

4th radical of (a^2/b) solve what? There is no equation here.

2+ √3)/(2-√3) = 4 - 3 = 1

log4 + logx =28 \\ now this I can solve
Log(4x) = 28 \\ i assume this is base 10
10^(log(4x)) = 10^28
4x = 10^28
x = (1.0*10^28)/4 = 0.25*10^28 = 2.5*10^27
= 2,500,000,000,000,000,000,000,000,000
