Given :-

  • (9^{2} )^{-1/3}

To Find :-

  • To solve the expression .

Solution :-

Given expression to us is ,

(9^{2} )^{-1/3}

We know that ,

9 = 3^2

So our expression becomes ,

\{ (3^2)^2\}^{\frac{-1}{3}}

And , (a^m)^n =a^{mn} . Using this ,

(3^4)^{\frac{-1}{3}}

Again using the same law ,

3^{\frac{-4}{3}}

We know that , a^{-m}=\frac{1}{a^m} . Therefore ,

(3^{-4})^{\frac{1}{3}}

\\\bigg( \dfrac{1}{3^4}\bigg)^{1/3}

\\ \dfrac{1}{\sqrt[3]{3^4}}

Simplify ,

\dfrac{1}{3\sqrt[3]{3}}

This is the simplified expression.

<em>I </em><em>hope</em><em> this</em><em> helps</em><em>.</em>

The area of a square rug can be represented by the expression 100x^2+60x+9. Write an expression to represent the length of each
Ganezh [65]
ANSWER:

square root of ( 100x^2 + 60x + 9 )

An expression to represent the length of each side of the rug is:
square root of ( 100x^2 + 60x + 9 )

STEP-BY-STEP EXPLANATION:

Let's establish that the area of a square is the length of one of its sides squared.

Area of square = Side^2

THEREFORE:

To find the length of each side of the square, we will make side the subject in the formula as displayed below.

Area of square = Side^2

Side^2 = Area of square

Side = square root of ( area of square )

From this, we will substitute the given expression for the area of the square rug to obtain the expression for the length of each side of the rug.

Side = square root of ( 100x^2 + 60x + 9 )
