Given:

To find:
The value of given expression by using the Laws of Exponents.
Solution:
We have,

Using the Laws of Exponents, we get
![[\because a^ma^n=a^{m+n}]](https://tex.z-dn.net/?f=%5B%5Cbecause%20a%5Ema%5En%3Da%5E%7Bm%2Bn%7D%5D)

![[\because \left(\dfrac{a}{b}\right)^n=\dfrac{a^n}{b^n}]](https://tex.z-dn.net/?f=%5B%5Cbecause%20%5Cleft%28%5Cdfrac%7Ba%7D%7Bb%7D%5Cright%29%5En%3D%5Cdfrac%7Ba%5En%7D%7Bb%5En%7D%5D)


Therefore, the value of given expression is
.
Answer:
terms, 2x, 3y , x and 7,
like terms, 2x, 3y, x and 7
Coefficient. 2 is the coefficient of 2x and 3 is the coefficient of 2y 1 is the coefficient of x
Constant. 7
Step-by-step explanation:
Given:

Terms are the number of parts in the expression.
there are four terms 2x, 3y , x and 7,
Like terms are the part of the polynomials. 2x, 3y and x are like terms because they both have an x attached. 7 is like terms because they have nothing attached.
The number that are attached to variable is called Coefficient.
So In the term 2x the number 2 is a coefficient because it is attached to x similarly 3y the number 3 is a coefficient because it is attached to y
and in the term x the number 1 is a coefficient.
Constant are the numbers that are not attached to any variable and it is not change. Such as 7 is the constant term.
