Question

MEDALS!

Erika was working on solving the exponential equation 50x = 17; however, she is not quite sure where to start. Using complete sentences, describe to Erika how to solve this equation and how solving would be different if the bases were equal.

Answer 1

nErika could solve with a calculator and do trial and error until she found some power of 5 that would equal 17 (it's a little above 1.76 by this method). But being a smart person, Erika would see that the best solution would be to take logs of both sides

Log 5^x = log 17....... Erika knows that log 5^x = x(log 5)
x(log 5) = log 17
0.69897x = 1.2304489....divide across by 0.69897
x = 1.76055, a much more precise solution

Answer 2
