Question 9 • Mathematics III

Which of the following shows the equation log sub 4 of open paren x plus 6 close paren is equal to 2 rewritten using logarithms?

Answer
A
4 raised to the log sub 4 of open paren x plus 6 close paren power is equal to 4 to the 4th power
B
log sub 4 of open paren x plus 6 close paren is equal to the log base 4 of 16
C
log sub 4 of open paren x plus 6 close paren is equal to the log base 2 of 16
D
4 raised to the log sub 4 of open paren x plus 6 close paren power is equal to 2 squared

Explanation

Since 4² = 16, the definition of a logarithm gives log₄(16) = 2. So the equation can be rewritten as log₄(x + 6) = log₄(16), which is choice D.
