oof

remember some rules

(a/b)(c/d)=(ac)/(bd)


(x^a)/(x^b)=x^(a-b)


x^0=1


(x^a)(x^b)=x^(a+b)


x^(-a)=(1)/(x^a)



((7^(-3))(7^(-2))(2^0))/((7^(-1))(7^(-4))(2^3))=


((7^(-3-2))(2^0))/((7^(-1-4))(2^3))=


((7^(-5))(2^0))/((7^(-5))(2^3))=


((7^(-5))/(7^(-5)))((2^0)/(2^3))=


(7^(-5-(-5)))(2^(0-3))=


(7^0)(2^(-3))=


(1)/(2^3)=


(1)/(8)
