343

Step-by-step 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: $\frac{7^7}{7^4}$ .

Remember another exponent rule where if we have $\frac{a^b}{a^c}$ , this is equal to $a^{b-c}$ .

So, $\frac{7^7}{7^4}=7^{7-4}=7^3=343$ .

The answer is thus 343.
