30log2 translate English

Logx = log ( 2 ^ 30 * 10 ^ - 7 ) logx = 30log2 - 7log10 logx = 30 * 0.3 - 7

Logx = log ( 2 ^ 30 * 10 ^ - 7 ), logx = 30log2 - 7log10 logx = 30 * 0.3-7

logx = log ( 2 ^ 30 * 10 ^ - 7 ) logx = 30log2 - 7log10 logx = 30 * 0.3-7 logx = 2.

And you apply logarithm on each side logx = log logx = 30log2 - 7log10 logx = 30 * 0.3 - 7 logx = 2 So, the X is 100
