Answer:

$7^{12}$

Step-by-step explanation:

When you divide two numbers that have exponents and have the same base, just subtract the exponents. In this case, 7 is the base of both the dividend and the divisor. So, simply subtract 14 - 2 to get 12. The final answer is $7^{12}$ .

Hope this helps! :)

Hello!

3 x - 40^0 = 2 x - 10^0
