Multiple Choice
Write each expression using a single exponent.
x to the ninth over x squared
A. x11
B. x7
C. 7
D. x5
The answer is: x^(9-2) = x^7
Therefore, the answer is (B) x^7
To write the given expression using a single exponent, we subtract the exponent in the denominator from the exponent in the numerator.
x to the ninth over x squared can be written as x^(9-2), which simplifies to x^7.
Therefore, the correct answer is B. x^7.
