1)Without using tables, show that

(log√125 + log √27 - √8)/ log 15 - log 2 = 3/2

What i tried was

(3/2 log 5 + 3/2 log 3 - 3/2 log 2)/ log 5+log 3 - log2

then from here I don't know where to take it.

2) Find the value of x if log x

I tried this 2logx - 2loga = 4 log y- log y

2logx = 3logy+ 2 loga

then here I get stuck..

(log√125 + log √27 - √8)/ log 15 - log 2 = 3/2

(3/2 log 5 + 3/2 log 3 - 3/2 log 2)/ log 5+log 3 - log2

2) Find the value of x if log x

^{2}/ log a^2 = log y^4/logyI tried this 2logx - 2loga = 4 log y- log y

2logx = 3logy+ 2 loga

then here I get stuck..
