Answer:

So the equation in standard form will be x^{\frac{-1}{3}}  

Step-by-step explanation:

We have given equation x^{\frac{-2}{3}}\times x^{\frac{1}{3}}

We have to write this expression in standard form

For writing in standard form first we have to do operation on the expression

We know that there is property of exponent that when two functions are multiplied with each other then there exponent are added

So x^{\frac{-2}{3}}\times x^{\frac{1}{3}}=x^{\frac{-2}{3}+\frac{1}{3}}=x^{\frac{-1}{3}}

So the equation in standard form will be x^{\frac{-1}{3}}

Which property is illustrated?
Marat540 [252]

Option D- Commutative property of addition.

<u>Answer: </u>

18 + 9 = 9 + 18 which illustrate commutative property of addition.

<u>Solution: </u>

Step 1:

The given data is a commutative property of addition, because no-matter where we put the numbers, you will always get the same answer. This can be represented by a + b = b+ a

Step 2:

From the given Data

18 + 9 = 9 + 18  

When we add LHS and RHS we get the same answer 27.

Step 3:

If we exchange the numbers in this problem then also you will get the same answer.

9 + 18 = 18 + 9 which gives 27.  

Result:

Hence we come to the conclusion; the given data illustrates commutative property of addition.
