Evaluate the expression without using a calculator.
log7 1/root:7 Answer by stanbon(75887) (Show Source):
You can put this solution on YOUR website! Use properties of logarithm to expand the logarithmic expression as much as possible. Where possible, evaluate logarithmic expressions without using calculator.
log4(4/x) = log4(4) - log4(x) = 1 - log4(x)
------------------------------------------------------
Evaluate the expression without using a calculator.
log7 1/root:7
log7(1/sqrt(7))
= log7(1) - log7(sqrt(7))
= 0 -(1/2)log7(7)
= 0-1/2
= -1/2
