Write the given exponential equation in logarithmic form. 5a" - 6=0 The logarithmic form isWrite the given expression in an expanded form. Assume that variables represent positive numbers. FE x2+8 '"2i x47_ x2+8 (Do not simpiify.) Write the given expression in condensed form. 1 - log x - log (5y) + log (3z) 1 - log x - log (5y) + log (3z) = (Type an exact answer. Use integers or fractions for any numbers in the expression.)Use the change of base formula to approximate the following expression. log 5? + logs!) What is the value of log 5? + log 59? (Simplify your answer. Type an Integer or a deCImai rounded to the nearest thousandth as needed.) Determine the haillife of the substance that decays from A0 to A in time t. An:48, A:1T, t:12 years The haltlite of the substance is years. (Do not round until the nal answer. Then round to one decimal place as needed.)
