What is the volume occupied by 8 grams of oxygen in `m^3` at 3 atm and `27^oC`?
(a) `2.05 X 10^-3`
(b) `4.1 X 10^-3`
(c) `2.5 X 10^-3`
(d) `4.2 X 10^-3`

Write the following numbers in the usual form: 4. 83\ x\ 10^7 (ii) 3. 02\ x\ 10^(-6) 4. 5\ x\ 10^4 (iv) 3\ x\ 10^(-8) 1. 0001\ x\ 10^9 (vi) 5. 8\ x\ 10^2 3. 61492\ x\ 10^6 (viii) 3. 25 x\ 10^(-7)

If 2x+3y=5 and 3x+2y=10 then x-y= (a) 3 (b) 4 (c) 5 (d) 6

8a ^ (2) -27ab + 9b ^ (2), 3x ^ (3) -x ^ (2) -10x

(b) Factorize 4x^(3) - 10y^(3) - 8x^(2) y + 5xy^(2)

Find HCF of 10x^(3)-10x^(2)-5x + 9 " &" 30x^(3)-61x^(2)-24x + 10

Simplify : 7x + 3x(x-4) = ? A. 10x + 12 B. 10x - 12 C. 3x^(2) + 5x D. 3x^(2) - 5x

((4x-3) / (2x + 1))-10 ((2x + 1) / (4x-3)) = 3, x! =-1/2, 3/4

If 2x+y=5 and 3x-4y=2, then the value of 2xy is (a) 4 (b) 6 (c) 8 (d) 10

If (a,4) lies on the graph of 3x+y=10 then the value of a is 3(b)1(c)3(d)4
