" Evaluate: "(3^(-5)times10^(-5)times125)/(5^(-7)times6^(-5))

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

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

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

Evaluate : ( 3^-5 times a^-6 times b^-4) /( 3^-6 times a^-5 times b^-3 )

Evaluate: (-7) times 8 times (-5) times (-6)

Evaluate : ( -5 )^6 times ( -5 )^8 times ( -5 )^3

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

Evaluate : (-5) times (-5) times (-5) times ............ 5 times

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))
