First, rewrite 16/25 and 13/20 so that they have a common denominator.
Akimi4 [234]

Answer:

The answer to your question is 64/100 and 65/100

Step-by-step explanation:

Data

Common denominator of   16/25 and 13/20

Process

1.- Find the least common factor of 25 and 20.

                            25      20      2

                            25      10       2

                            25        5       5

                              5         1       5

                               1

   L.C.F. = 2 x 2 x 5 x 5 = 100

2.- Convert each fraction to the denominator 100

           100 / 25 = 4

            16/25 = (16 x 4) / 100

                     = 64/100

            100 / 20 = 5

            13/20 = (13 x 5)/100

                      = 65/100

Give a power series representation for the function f(x) x^3/(1 + 9x^2)
Nata [24]

Recall that for |x|, we have

\displaystyle\frac1{1-x}=\sum_{n\ge0}x^n

Replace x with -9x^2 and we get

\displaystyle\frac1{1-(-9x^2)}=\sum_{n\ge0}(-9x^2)^n=\sum_{n\ge0}(-9)^nx^{2n}

Lastly, multiply this by x^3, so that

\boxed{f(x)=\displaystyle\sum_{n\ge0}(-9)^nx^{2n+3}}
