What is te logarithmic form of the solution to 1312 017 x 13

What is te logarithmic form of the solution to (13.1)2\' 0.17 x 13. ilog,0.1 x log 13.1 log,0.1 x ogo, 113.1 Back Next

Solution

4) (13.1)2^x = 0.1

Divide both sides by 13.1

2^x = (0.1/13.1)

take natural log on both sides:

x*ln2 = ln(0.1/13.1)

x =ln(0.1/13.1)/ ln2

= ln2(0.1/13.1)

Option B

5) e^5x = 9.3

Take natural log on both sides:

5x = ln(9.3)

x = ln(9.3)/5

Option C
