Logx105log10x 4Solutionlogx10 5log10x 4 Use the log prope

Log_x10=5log₁₀x + 4

Solution

logx^10 = 5log10x +4

( Use the log property : logA^x = xlogA)

(Use the log property : logA*B = log A +logB)

10*logx = 5log10 + 5logx +4

10logx - 5logx = 5log10 +4

5logx = 5log10 +4

5logx = 5*1 +4

5logx = 9

logx = 9/5

x = 10^9/5

x = 10^1.8
