Answer: Solution Step-by-step explanation: Rewrite logx729= 3 is an exponential form using the definition of a logarithm. If x and b are positive real numbers and b≠1, then logb(x)= y is equivalent to b^y = x. X^3 = 729 Take cube root on both side and we get x= 3√729 now we firstly simplify the 3√729 Rewrite 729 as 9^3 x = 3√9^3 pull terms out from under the redical, assuming positive real numbers x=9 verify each of the solution by substituting them into logx729=3 and solving. x= 9
