Question

What is the solution to the equation below? Round your answer to two decimal places.

10 log(4x) = 25

A. x = 316.23
B. x = 93.78
C. x = 79.06
D. x = 1264.91

Answer 1

1.) Isolate log(4x) by dividing both sides by 10.

Answer 2

Divide both sides by 10
log 4x = 25/10 = 2.5
Raise 10 to the 2.5 power
4x = 10 ^ (2.5)
and then divide the answer by 4
x = 10 ^(2.5) / 4 = 79.056

Answer 3

log(4x)=5/2

Answer 4
