Question 368909
log^81+2log4-log(3)

To find an approximate value of log4, use the formula log^ng81=(ln(g81))/(ln(n)).
g81lo+((2ln(4))/(ln(10)))-log(3)

Find the value of each expression using a calculator.
g81lo+(20.60206)-log(3)

To find an approximate value of log(3), use the formula log^ng81=(ln(g81))/(ln(n)).
g81lo+(20.60206)+(-(ln(3))/(ln(10)))

Find the value of each expression using a calculator.
g81lo+(20.60206)+(-0.4771213)

Remove the parentheses that are not needed from the expression.
g81lo+20.60206-0.4771213

Subtract 0.4771213 from 20.60206 to get 20.12494.
g81lo+20.12494
