The maximum value of `(log)_(20)(3s in x-4cos x+15)-` a.`\ 1` b. `2` c. `3` d. `4`

The minimum value of f(x)=3cos x + 4sin x is ………..

If sin^ 4 x/2+cos^4 x/3 =1/5 then

The maximum & minimum value of y=x+(1)/(x) in interval [(1)/(3),(4)/(3)]

Solve for x :(log)_4(log)_3(log)_2x=0

The number of solutions of (log)_4(x-1)=(log)_2(x-3) is (2001, 2M) (a) 3 (b)1 (c) 2 (d) 0

The value of expression, (log)_4((x^2)/4)-2(log)_4(4x^4) when x=-2 is (a) -6 (b) -5 (c) -4 (d) meaningless

Value of [2/((log)_4(2000)^6)+3/((log)_5(2000)^6)] is a. 4^(1/3). 5^(1/2) b. 1/6 c. 3 3 d. none of these

If log_2 log_3 log_4 (x+1) =0, then x is :-

If x^2+y^2=4 then find the maximum value of (x^3+y^3)/(x+y)

Let f(x)=|1+sin^2x cos^2x4sin2xsin^2\ \ x1+cos^2x4sin2xsin^2xcos^2x1+4sin2x|,\ then the maximum value of f(x)= a. 2 b. 4 c. 6 d. 8
