9.2 xx 8.8 = 72.96

If 7 xx 3 -: 8 = 80 , then 8-: 2 xx 9 = ?

Evaluate |(1, 2, 3),(7, 8, 9),(3, 2, -1)|

8a ^ (2) -27ab + 9b ^ (2)

8 cot^2A-8 cosec^2A is equal to a) 8 b) 1/8 c) -8 d) - 1/8

If A = {1,2,3……..9} , B = {2,4,6,7,8} and C = {3,4,5,8,9,10} then (A - B) uu C is .

Solve (9xy + 7 xy + 9x ^(2)) + ( 8 + x ^(2) - xy - y ^(2) + 1).

How many 8's followed by an even number and preceded by an odd number? 7, 8, 5, 6, 7, 8, 4, 3, 2, 1, 3, 8, 6, 4, 3, 7, 8, 4, 2, 1, 3, 8, 2, 8, 9

4 1/2+(1-:2 8/9)-3 1/13=
