`(a^atimesa^atimesa^atimes..........a^a)`[a times]

(i) Write in exponential form: q times q times qtimes q times ........15 times

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)8times x times x times y times y times y

If vectors barb, bar c ,bard are not coplanar then prove that (bara times barb) times (barc times overlind)+(bara times barc) times (bard times barb)+(bara times bard) times (barb times barc) is parallel to bara .

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

bara times (barb times barc) +barb times (barc times bara)+ barc times (bara times barb) equals

Evaluate a^(7)times b^(7)times c^(-4)times c^(5)times d^(9)

If atimes(btimesc)=0 , then

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

Evaluate: (1) times (1) times (1) times (1) times (-1) times (-1) times (-1) times (-1) times (-1) times (-1) times (-1)

Evaluate a times a times c times c times c times c times d
