Find the sum upto n terms of the series 0.b+0.b b+0.b b b +0.b b b b+"......",AA " b" in N " and "1 le b le 9.

For any real number b, let f (b) denotes the maximum of |sin x+(2)/(3+sin x)+b|AA x in R. Then the minimum vlaue of f (b) AA b in R is:

If a, b represents two distinct positive integers and thus (aa)^b = abba is a valid relation. Then the value of (a^b . b^a + b^a .a^b) is :

If Delta=det[[0,b-a,c-aa-b,0,c-ba-c,b-c,0]], then Delta

Show that det[[0,b-a,c-aa-b,0,c-ba-c,b-c,0]]=0

How many pairs of positive integers (a,b) are there such that a and b have no-common factor greater than 1 and (a)/(b)+14(b)/(a) is aa integer:

If ' a ' is a natural number and ' b ' a digit such that (3a+2007)^2=4b 85924 , then a.a-b=31 b. a+b=37 c. a+b=41 d. a-b=33
