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.

2p+6a=$14
3p+9a=$21

3p+9a=21
Subtract 9a
3p=21-9a
divide all by 3
p=7-3a
plug it into start equations

2p+6a=14
2(7-3a)+6a=14
14-6a....+6a=14

this zeroes out...
