SOLUTION: solve each equation or inequality round to four decimal places... 2.4^(x+4)=30 so far i have (x+4) log2.4 = log 30 x+4 = log30/log2.4 x = (log30/log2.4) -4 and now im l

Question 747855: solve each equation or inequality round to four decimal places...
2.4^(x+4)=30

so far i have (x+4) log2.4 = log 30
x+4 = log30/log2.4
x = (log30/log2.4) -4
and now im lost???

You're right. Now on a calculator simplify log30/log2.4 and get approx 3.885. Now subtract four. That's your answer. Because its negative make sure to check your answer back in the original problem. In this case, it does work.
