Where b is a positive real number, and the argument x occurs as an exponent For real numbers c and d, a function of the form () = is also an exponential function, since it can be rewritten as = () As functions of a real variable, exponential functions are uniquely characterized by the fact that the growth rate of such a function (that is, its derivative) is directly proportional to theMulitplying the Outisde two components together (x and 3) gives 3x Multiplying the Inside two components together (2 and x) gives 2x and multiplying the Last two components together (2 and 3) gives 6 Adding all this together gives x 2 3x2x6 3x and 2x can be added together to give 5x so this simplifies to x 2 5x6 which is the answer · 3(x4) is the same as 3x12 when the brackets are expanded out

In the previous section you learned that the product A(2x y) expands to A(2x) A(y) Now consider the product (3x z)(2x y) Since (3x z) is in parentheses, we can treat it as a single factor and expand (3x z)(2x y) in the same manner as A(2x y) This gives us If we now expand each of these terms, we have(x y) 7 = x 7 7x 6 y 21x 5 y 2 35x 4 y 3 35x 3 y 4 21x 2 y 5 7xy 6 y 7 When the terms of the binomial have coefficient(s), be sure to apply the exponents to these coefficients Example Write out the expansion of (2x 3y) 4 · write the cubes in expanded form (x2/3y)3 Maths Polynomials NCERT Solutions;
