Write the expression using a single exponent.
Ipatiy [6.2K]

Answer:  D.  7^11

Reason:

The rule we use is a^b*a^c = a^{b+c}

When multiplying exponentials of the same base, we add the exponents.

The exponents 5 and 6 add to 5+6 = 11

So,

7^5 \times 7^6 = 7^{5+6} = 7^{11}

The base stays the same the entire time.
