Question

identify in the given expressions, terms which are not constants. give their numerical coefficients. (i) 5x – 3 (ii) 11 – 2y2 (iii) 2x – 1 (iv) 4x2y + 3xy2​

Answer 1

(i)

Given,

5x-3

To Find,

We have to find numerical coefficients.

Solution,

Numerical coefficients are number or constants that are written along with variables. Variables are those entities in math which change their values from time to time and therefore they are not constant or they do not have fixed value.

We need to understand that usually English alphabets are used in mathematics to represent variables. For example x,y,t,etc alphabets are used to represent non-constant values.

In the question given 5x-3,

we can see "x" is the variable and numerical value written in front of it will be numerical coefficient.

So here 5 is written in front of it so it is the numerical value.

Numerical coefficient in  5x – 3 of x is 5.

(ii)

Given,

11 – 2$y^{2}$

To Find,

We have to find numerical coefficients.

Solution,

In the question given 11 – 2$y^{2}$,

we can see "$y^{2}$" is the variable and numerical value written in front of it will be numerical coefficient.

So here 2 is written in front of it so it is the numerical value.

Numerical coefficient in  11 – 2$y^{2}$ of  $y^{2}$is 2.

(iii)

Given,

2x – 1

To Find,

We have to find numerical coefficients.

Solution,

In the question given 2x – 1,

we can see "x" is the variable and numerical value written in front of it will be numerical coefficient.

So here 2 is written in front of it so it is the numerical value.

Numerical coefficient in  2x – 1 of  x is 2.

Given,

$4x^{2} y + 3xy^{2}$

To Find,

We have to find numerical coefficients.

Solution,

In the question given $4x^{2} y + 3xy^{2}$,

we can see here we have two terms separated by addition operator.

First we see "$x^{2} y$" is the variable and numerical value written in front of it will be numerical coefficient.

So here 4 is written in front of it so it is the numerical value.

Second we see "$xy^{2}$ "is the variable and numerical value written in front of it will be numerical coefficient.

So here 3 is written in front of it so it is the numerical value.

Numerical coefficient in $4x^{2} y + 3xy^{2}$ of $x^{2} y$ is 4 and $xy^{2}$  is 3 .
