No. of term in (1 + 5sqrt2x)^9 + (1 - 5sqrt2x)^9 if x > 0 is

No. of term in (1 + 5sqrt2x)^9 + (1 - 5sqrt2x)^9 if x > 0 is

Find the number of terms in the following expansions. (vi) (1+ 3 sqrt(5) x )^(9) - (1-3 sqrt(5) x)^(9)

The number of terms in the expansion of (1+7sqrt(2x))^9+(1-7sqrt(2x))^9 is

The number of nonzero terms in the expansion of (1+3 sqrt2 x)^9 + (1-3 sqrt2 x)^9 is

If (9+4sqrt(5))^(x)+(9-4sqrt(5))^(x)=18 then the value of x^(2)-(1)/(x^(2))

(9+4sqrt(5))^(x)+(9-4sqrt(5))^(x)=18, then find x^(2)-(1)/(x^(2))

Using properties of proportion, solve for x : (i) (sqrt(x + 5) + sqrt(x - 16))/ (sqrt(x + 5) - sqrt(x - 16)) = (7)/(3) (ii) (sqrt(x + 1) + sqrt(x - 1))/ (sqrt(x + 1) - sqrt(x - 1)) = (4x -1)/(2) . (iii) (3x + sqrt(9x^(2) -5))/(3x - sqrt(9x^(2) -5)) = 5 .
