let t = 7× 7² * t + t = 70 50t = 70 5t = 7 t = 7/5 7× = 7/5 log(7×) = log(7/5) x * log(7) = log(7) - log(5) log(7) - log(5) x = --------------------- log(7) log(5) x = 1 - --------- log(7)

7^x(7²+1)=70 7^x=7/5 x=(log7-log5)/log7=1-log5/log7 x≈1-0.699/0.845≈146/845≈0.1728 Deviation is about 0.0001 7^2.1727+7^0.1728≈69.985
