Answer:

343

Explanation:

In the top, let's first solve the subtraction expression within the parentheses:

12 - 5 = 7

So, the numerator is
7^7.

Now solve the addition expression within the parentheses in the denominator:

3 + 4 = 7

So, the denominator is
(7^2)^2.

Remember the exponent rule, where if we have
(a^b)^c, then it is equal to
a^(b*c)=a^(bc).

So,
(7^2)^2=7^(2*2)=7^4.

Now, our expression is:
(7^7)/(7^4).

Remember another exponent rule where if we have
(a^b)/(a^c), this is equal to
a^(b-c).

So,
(7^7)/(7^4)=7^(7-4)=7^3=343.

The answer is thus 343.
