Question

Log3(5x+1)=4 A.) x = 5 B.) x = 16 C.) x = 4 D.) x = 3

Answer 1

B) x=16

Explanation:

The 3 is the base, the expression in the parenthesis is the argument and the 4 is the exponent

We also know that
`base^(exponent)` = argument

so therefore the new equation is
`3^(4)` = 5x+1

3 to the fourth power is 81

so 81=5x+1

then solve algebraically
