verify :
`a times b = b times a` , if a = `2/3` and b = `-7/2`

Evaluate : ( a^3 times b^2 times b^3 times a^2 ) / ( a^2 times b )

Evaluate : ( a^(-4 ) times b^(-7 ) times c^(-3) times d^3 ) / ( a^(-7) times b^(-9 ) times c^3 times d^3 )

Evaluate : ( a^2 times a^3 times b^3 times b^4 ) / ( a^5 times b^2 )

Evaluate value of x : ( a^-3 times b^-4 )/( a^-2 times b^-3 ) = a^-x times b^-x

Express the following in exponential form: (i) "6 times 6times6 times 6 (ii) t times t (iii) b times b times b times b times b times b (iv) 5 times 5times7 times 7times7 (v) "2 times 2times a times a (vi) a times a times a times c times c times c times c times d times 1

Solve : ( a^(-2) times b^(-3) times c^2 )/ ( b^-4 times c^-3 )

(a^(3)times b^(2)times a^(2)times b)^(3)

Evaluate : ( 9^3 times a^5 times b^2 ) / ( 3^6 times a^3 times b )

Evaluate : ( a^4 times b^5 times c^7 )/ ( c^8 times a^4 times b^3 )

Evaluate : ( a^4 times b^5 times c^7) / ( c^8 times a^4 times b^3 )
