`b times b times b times b`

Evaluate : 13 times 13 times 13 times a times a times a times a times a times b times b times b times b

Evaluate : b times b times b times b

Write the following in the exponential form: (a) b times b times b times...10 times (b) y times y times...15 times (c) 9times a times a times a times b times b times b times b times b (d) 18 times xtimesxtimesytimesytimesy

Evaluate : 8 times b times b times b times a times a times a times a

The point of intersection of the lines r times a=b times a, r times b=a times b is

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

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

If a, b and c are any three vectors, then a times (b times c)=(a times b) times c if and only if

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

Let a-i+j and b=2i-k .The point of intersection of the lines r times a=b times a and r times b=a times b is
