Step-by-step explanation:
Use the exponent laws to identify which law to use.
1. y^-4 * y^-5 = y^-9
(add the exponents)
2. (m^-3)^5 = m^-3*5 = m^-15
(multiply the exponents)
3. n^-3 * n^6 = n^3
(add the exponents)
4. m^-12/m^-6 = m^-12-(-6) = m^-6
(subtract exponents)
5. (n^-2)^-2 = n^-2*-2 = n^4
(multiply the exponents)
6. w^5/w^-7 = w^5-(-7) = w^12
(subtract the exponents)
7. 2^-3 * 2^-2 = 2^-5
(add the exponents)
8. (-6)^4 * (-6)^-3 = -6^1
(add the exponents)
9. (4^-6)^0 = 4^-6*0 = 4^0 = 1
(multiply the exponents)
