Simplify (3^(-5)times5^(-7)times(-2)^(3))/(3^(4)times5^(-2)times(-2)^(-3))

5(1)/(7)times3(2)/(4)

(3^(-5)times10^(-5)times125)/(5^(-7)times6^(-5))

A real number (2^(2)times3^(2)times7^(2))/(2^(2)times5^(3)times3^(5)times7^(4)) will have

Evaluate : (5/7)^3 times ( 5/7 )^(-6) times ( 1/3 )^(-2 ) times ( 3/5 )^-2

[((-2)/(-3))times(1)/(5)]times((-2)/(7))=((-2)/(-3))times[(1)/(5)times((-2)/(7))]
