Simplify each expression. Assume all variables represent

nonzero real numbers.

-40^0- 30^0

Anything to the 0 power equals 1.

-40^0 - 30^0
-1 - 1 = -2

To simplify the given expression, we need to evaluate the exponents.

The exponent 0 indicates that any number raised to the power of 0 is equal to 1.

So, -40^0 equals -1, and 30^0 equals 1.

Therefore, the simplified expression is -1 - 1, which equals -2.
