The value of `(9! )/ (3! 6!)` is........

Find the value of 3^(2log_(9)3) .

(a) Find the value of x if 1 + 6 + 11 + ... + x = 189. (b) Find the value of x if 3 + 6 + 9 + ... + 96 = x.

If y = (1)/(3) + (1*3)/(3 *6) + (1 * 3*5)/(3*6*9) +… then the value of y^(2) + 2y is a. 2 b.-2 c. 0 d . None of these

If the curves y^2=6x , 9x^2+by^2=16 intersect each other at right angles then the value of b is: (1) 6 (2) 7/2 (3) 4 (4) 9/2

The value of |{:(1, 2, 3),(-4, 3, 6),( 2,-7, 9):}| is a.213 b.-231 c.231 d. 39

Find the value of : 6-9+4

Find the value of (-6)/(2/3) options are 1] -9 2] 9 3] -4 4] -4/3

If (45)/(60) is equivalent to 3/x , then the value of x is (a) 3 (b) 6 (c) 4 (d) 9

Q. If 2[[x,9],[y,6]]+3[[1,-1],[0,2]]=[[9,15],[12,18]], then the values of (x+y) is (A) 3 (B) 9 (C) -1 (D) -2

Q. If 2[[x,9],[y,6]]+3[[1,-1],[0,2]]=[[9,15],[12,18]], then the values of (x+y) is (A) 3 (B) 9 (C) -1 (D) -2
