Question 4 • Mathematics III

Which logarithmic equation has the same solution as x minus 4 is equal to 2 cubed ?

Answer
A
log 2 cubed is equal to open paren x minus 4 close paren
B
log sub 2 times open paren x minus 4 close paren is equal to 3
C
log sub 3 times open paren x minus 4 close paren is equal to 2
D
log 3 squared is equal to open paren x minus 4 close paren

Explanation

The equation is x − 4 = 2³, which has the exponential form 2³ = x − 4. Using the equivalence aᵇ = c ⇔ logₐ(c) = b, this becomes log₂(x − 4) = 3. So the matching equation is choice B, “log base 2 of (x − 4) equals 3.”
