Answer:
1, -1
Explanation:
(-2/3)⁰
Anything that is raised to the power of 0 automatically becomes the value 1. Knowing this, apply the exponent.
(-2/3)⁰ = 1
-(7)⁰
Now using what we know, apply the exponent to the 7.
-(7)⁰ = -1
Notice that the negative is NOT inside the parenthesis and therefore does NOT get affected by the power.
