How do I use Negative and Zero Exponents

Zero exponent is nothing

Well negative exponents you use as normal like a negative and do normal mathfor example:

x to the power of - 5 + x to the power of - 3

you know you its like - 5+-3 but in exponent form so you do normal math

-5+-3=-8

but with zero exponents any variable or number with a zero exponent equals 1 for example:

6 to the power of 0 = 1
