Question

Solve:

Log4 (x+3) = Log49

Select the appropriate response:

A) x=3
B) x=6
C) x = -12
D) x=9

Answer 1

B) x = 6

Explanation:

log4(x + 3) = log4(9)

x + 3 = 9

x = 9 - 3

x = 6

Answer 2

x=6

Explanation:

log 4 (x+3) = log4 9

Since the bases are the same

x+3 = 9

Subtract 3 from each side

x+3-3=9-3

x=6
