Question

I’ve tried many times to get the answer. I looked on another app but I still don’t understand how they got they’re answer, I keep ending up with the same answer 2.6

Answer 1

Explanation:

10 ln (100x) -3 = 117 note this is the NATURAL logarithm (not base 10 LOG)

10 ln (100x) = 120

ln(100x) = 12 now e^x both sides

100x = e^12

100x = 162 754.79

x= 1627.55
