Use your knowledge of exponents to solve.
So I know that these functions are rational functions.. and I am trying to solve for x. I tried to solve them by I keep getting stuck with the exponent 2 which is the exponential function.. Help please
a) the first one is solved by inspection, x=0 is the only solution.
b) the second is solved by inspection, if x=2 the sides are equal, so then try on each side. If x=1 or x=3, is it true?
1/2?>1 False, so x cannot be <2
1/8?>1/9 True, so x>2
