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

(5)/(7)times(5)/(7)times(5)/(7)times(5)/(7)

" (f) (5^(6)times a^(7))/(5^(2)times a^(3)times(10)^(0))

Evaluate: (-3) times (-4) times (-5) times (-6) times 7

((5)/(6))times((-2)/(5)+(3)/(10))

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

Simplify. (i) (25 xx t^(-4))/(5^3 xx 10 xx t^(-8)) (t != 0) (ii) (3^(-5) xx 10^(-5) xx 125)/(5^(-7) xx 6^(-5))

[8^(-2/3)times2^(1/2)times25^(-5/4)]÷[32^(-2/5)times125^(-5/6)] =sqrt2

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)
