adding fractions with x

It is the ratio of number of moles of one component (solute or solvent) to the total number of moles of all the components (solute and solvent) present in the solution. It is denoted by the symbol X. Let us suppose that a solution contains two components A and B and suppose that n A mol..

What is the area of the shaded region in the figure, if the points X and Y are the mid-points of the sides AD and BC? => 8 m 2 or 20 m 2 or 16 m 2 or 24 m 2..

Rational function: If P(x) and Q(x) are two polynomials in x, then the ratio of two polynomials, P(x) / Q(x) is called a rational function, where Q(x) is not equal to zero. Proper rational function: If the degree of the num..

Particular Terms for Fractional Index - Sometimes, a particular term satisfying certain conditions is required in the binomial expansion of the type (1+x) n . This can be done by expanding (1+x) n to certain terms and then locating the required term. Generally this bec..

Binomial Theorem for Fractional Index - For any rational number n, We accept this expansion without proof. The restriction on x is not required when n is a natural number. Now, we shall see that when n is a natural number, then the above expansion coincides with that as given ea..

What fraction of the figure is shaded? Write the fraction in exponents form. => 2 2 x 3 2 or 2 2 3 2 or 3 2 2 2 or None of the above..

If x be numerically so small that its square and higher powers may be neglected, then (1+x) n = 1+nx (approximately), because x 2 , x 3 , x 4 ,. are all approximately zer..
