Evaluate :
`( b )   a^3 times b^3 ` 
`( d )   a^n times b^n times c^n times d^n`

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^(-7 ) times b^(-7 ) times c^5 times d^4 ) / ( a^3 times b^(-5 ) times c^(-3 ) times d^8 )

Show : ( a/b times c/d ) = ( a times c )/ ( b times d )

Evaluate : ( m^(-3) times n^4 ) /( n^2 times m^-8 ) ( m! = 0 , n != 0 )

"(a^(-3)times b^(-2)times c^(-5)times d^(5))/(a^(4)times b times c^(-3)times d^(4))

If A={a,b}. Then n(A times A) is :

If n(A times B)=6 and A={1,3} then n(B) is
