Time

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

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

If (a)/(b) is a rational number and n is a natural number then ((a)/(b))^(n)=(a)/(b)xx(a)/(b)xx(a)/(b)xx(a)/(b)xx....xx(a)/(b)=(a xx a xx a xx a xx...xx a)/(b xx b xx b xx b xx......xx b)=(a^(n))/(b^(n))

Let lambda=a xx(b xx c),mu=b xx(c xx a) and v=c xx(a xx b). Then

The unit digit of expression (1 xx 2 xx 3 xx 4 xx 5 xx 6 xx 7 xx 8 xx 9 xx 10)/(100) .

(137 xx 137 + 137 xx 133 + 133 xx 133)/(137 xx 137 xx 137 - 133 xx 133 xx 133) is equal to

The result of 9680 xx 10 xx 14 xx 0 xx 8 is :
