Question

Find the value of x. log 3 x = 4 A.) 7 B.) 12 C.) 27 D.) 81

Answer 1

Hello from MrBillDoesMath!

Answer:

Choice D, 81

Discussion:

By log 3x = 4 I presume that "3" is the base not a multiplier of x. Assuming it is the base, then the equation is equivalent to

x = 3^4

  = 81

This is Choice D.

Thank you,
