Evaluate the expression without using a calculator:
log4(2)= ____?

Use a calculator to find the logarithm accurate to four decimal places:
log4(27)= ____?

• Math -

log4(2)= ____?

What exponent must 4 be raised to, to obtain 2
that is,
4^? = 2
Isn't √4 = 2 ? or
4^(1/2) = 2

for the second,
log4 27
= log 27/log 4 , now use your calculator.
