Question

Need help with logarithm!! Show work. Just need #21, 24, 27 show work!!!

Answer 1

Answer:

For 24 is log base 4 of 2=x. Rewrite log base 4 (2)=x in exponential form using the definition of a logarithm. If x and b are positive real numbers and b does not equal 1, then log b (x)=y is equivalent to b^y=x. 4^x=2 . The answer would be 1/2.... For 27 is 3. For 21 is 3^x=1/3 3^x= 1/3^1 3^x= 3^-1 it is -1.
