Evaluate :

`( a^4 + b^4 ) times ( a^2 + b^2 ) times ( a + b ) times ( a - b )`

Evaluate : [ ( a times b ) times ( b times c ) ( b times c ) times ( c times a ) ( c times a ) times ( a times b ) ]

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

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

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

Evaluate : b times b times b times b

Evaluate ( 2^8 times a^5 times b^3 )/ ( ( 4^2 times a^2 times b )

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

Evaluate : a^2 times a^4 times b^5 times c^2 times b^2 times c^5
