eliminating logarithm from one side

eliminating logarithm from one side

azharrahman

Hi

Would really appreciate some help on this. How do you take exponents to remove log from the left and then make the 0 turn into a 1?

Thanks.

number in front of log is 1, 1 to the power of 0 is one thus log removed.

For the first part you just use the power rule for logs remember:

\displaystyle alog(x)=log(x)^a

.

For the second bit they use multiplication law:

\displaystyle log(x)+log(y)=log(xy)

.

For the last bit they have just took the exponential of both sides, remember

\displaystyle e^{log(x)}=x

and

e^0=1
