Answer 3

To simplify the expression 12(9−7^0)+(−29)^0, we need to evaluate the exponents first. Any number raised to the power of zero is equal to 1.

So, 7^0 = 1 and (-29)^0 = 1.

Now, the expression becomes:
12(9-1)+1

Simplifying further, we get:
12(8)+1

Finally, multiplying, we have:
96 + 1 = 97

Therefore, the equivalent expression is 97.
