The statement y = log base a of x is equivalent to which exponential statement?
Ay equals a to the power x
Ba equals x to the power y
Cx equals a to the power y
Da equals y to the power x
Answer & Solution
Correct answer: C. x equals a to the power y
1. A logarithm is the exponent that the base must be raised to.
2. So y is the exponent, a is the base and x is the result.
3. Writing that as an exponential statement gives x equal to a to the power y.
