If ƒ(x) = (5 − 2x ), then ƒ(−3) is

If 5-(2)/(x)=2-(5)/(x), then |(x)/(3)|=

If 2^(x).9^(2x+3) = 7^(x+5) , then x =

If x^(2)y = 2x - y and |x| lt 1 , then (( y + (y^(3))/(3) + (y^(5))/(5) + ….oo))/((x + (x^(3))/(3) + (x^(5))/(5) + ……oo)) =

If (3x -4y) : (2x -3y) = (5x -6y) : (4x -5y) , find : x : y .

Evaluate : (i) (2x - (3)/(5) ) (2x + (3)/(5) )

If (3^(2x-8))/(225)=(5^3)/(5^x) , then x= (a) 2 (b) 3 (c) 5 (d) 4

The integral int[2x^[12]+5x^9]/[x^5+x^3+1]^3.dx is equal to- (A) x^10 / (2(x^5 + x^3 +1)^2) (B) x^5/ (2(x^5 + x^3 +1)^2) (C) -x^10 / (2(x^5 + x^3 +1)^2) (D) - x^5 / (2(x^5 + x^3 +1)^2)

If |(3x,4),(5,x)|=|(4,-3),(5,-2)| , then x =

Subtract : 2x^(4) - 7x^(2) + 5x + 3 " from " x^(4) - 3x^(3) - 2x^(2) + 3
