Solve for b: 28=10^b+2 (Round to 4 digits.)

Answer 1

10^b = 26

b = log26

Answer 2

28 = 10^b +2

10^b = 28-2 = 26

10 to what power b = 26

1<b<2, b is closer to 1 than 2, 10 is closer to 26 than 100, 16 vs. 74 or over 4 times closer

just an educated "guesstimate" might be b = 1.25

take logs to the base 10

b = log26 =about 1.415
