What should come in place of the question mark(?) inthe following questions? (6)^(4)-:(36)^3 xx 216 = 6 ^(" ?-8")

3^(-5)times10^(-4)times(5^(4))/(5^(2))times6^(-5)=

Simplify ((125)/(216))^((2)/(3))xx((36)/(5))^(+2)div((25)/(6))^(-2)

solve it : (ii) (-3)/(5)times(-3)/(5)times(-3)/(5)times(-3)/(5) (iii) (-9)/(2)times(4)/(2)times(-4)/(2)times(-4)/(2)times(-4)/(2)times(-4)/(2) (iv) (-5)/(3)times(-5)/(3)times(-5)/(3)times(-5)/(3) (v) (-6)/(2)times(-6)/(2)times(-6)/(2)times(-6)/(2)times(-6)/(2)

Proved that (2)/(3)times[(-6)/(7)times(4)/(5)]=[(2)/(3)times(4)/(5)]times((-6)/(7))

What should be multiplied to 6^(-2) so that the product may be equal to 216? (a) 6^4 (b) 6^5 (c) 6^3 (d) 6
