What is the first step of the following division problem?

yanalaym [24]

Answer:

Divide 8x^3 by 2x

Step-by-step explanation:

Here, we want to identify the first step to take in the polynomial division.

When working with a polynomial division, what to do is to divide the first term of the dividend by the first term of the divisor ( the divisor is arranged in descending powers of x)

The number we want to divide is the dividend, while the number we are using to divide is the divisor.

In this case, the first term of the dividend is 8x^3 while that of the divisor is 2x

Perform the operation and write the answer in simplest form. 2 1/5 ÷ 31/5

Vinil7 [7]

<u>Answer:</u>

$\frac{11}{31}$

<u>Step-by-step explanation:</u>

We are given the following expression and we are to perform operation and write the answer in simplest form:

$\frac { 2 \frac { 1 } { 5 } } { \frac { 31 } { 5 } }$

Changing the mixed fraction into improper fraction:

$2\frac{1}{5}$ ---> $\frac{11}{5}$

Now simplifying it:

$\frac { \frac { 1 1 } { 5 } } { \frac { 31 } { 5 } }$

Changing the division sign to multiplication by taking the reciprocal of the denominator:

$\frac{11}{5} \times \frac{5}{31}$

$\frac{11}{31}$
