Prove that: (3^(-3)x6^(2)x sqrt(98))/(5^(2)x(1)/(25)3x(15)^(-(4)/(3))x3^((1)/(3)))=28sqrt(2)

Using (x + a) (x + b) = x^2 + (a+b) x + ab , find (i) 103 xx 104 (ii) 51 xx 52 (iii) 103 xx 98 (iv) 97 xx 98

If f(x) =5x^3 +4x^2 - 13 x-25 and f(x-3) = 5x^3 - 41 x^2 + 98 x + k then k=

If f(x) =5x^3 +4x^2 - 13 x-25 and f(x-3) = 5x^3 - 41 x^2 + 98 x + k then k=

Prove that: (3^(-3)\ xx\ 6^2xx\ sqrt(98))/(5^2\ xx\ root(3)(1/(25))\ xx\ (15)^(-4/3)\ xx\ 3^(1/3))=28sqrt(2)
