" काजए: (i) "9^((3)/(2))

Simplify: (9+4i) ((3)/(2)-i) (9-4i)

If 3x + (1)/(3x) = 3 , find : (i) 9x^(2) + (1)/(9x^2)

If 3x - (1)/(3x ) =5 , find : (i) 9x^(2) + (1)/( 9x^2)

Evaluate : (i) (3)/(7)+(-4)/(9)-(-11)/(7)-(7)/(9)

(i) (5^(2))^(7) = (ii) (7^(3)) (9^(3)) =

Analyze the roots of the following equations: (i) 2x^(3) - 9x^(2) + 12x - (9//2) = 0 (ii) 2x^(3) - 9x^(2) + 12x - 3 = 0

Find the sum: (i) (4)/(9)+(2)/(9) (ii) (3)/(8) + (1)/(8)+(5)/(8)
