Simplify :

`a^2 times b times c times a^(-1 ) times b^(-1) times c^(-1 )`

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

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

Evaluate : a times b times a times b times c times c times c

Evaluate : ( b times c ) times ( c times a ) =

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

a times a times a times b times b times c times c times c times c times c

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

Evaluate : ( 1/b + 1 ) times ( 1/c + 1 ) times ( 1/b ) times ( 1/c )
