How to right a radical in exponential form

Mathematics
1 answer:
Law Incorporation [45]3 years ago
3 0

Answer:

  \sqrt[n]{x}=x^{\frac{1}{n}}

Step-by-step explanation:

The index of a radical is the denominator of a fractional exponent, and vice versa. If you think about the rules of exponents, you know this must be so.

For example, consider the cube root:

\sqrt[3]{x}\cdot \sqrt[3]{x}\cdot \sqrt[3]{x}=(\sqrt[3]{x})^3=x\\\\(x^{\frac{1}{3}})^3=x^{\frac{3}{3}}=x^1=x

That is ...

\sqrt[3]{x}=x^{\frac{1}{3}} \quad\text{radical index = fraction denominator}

3 hrs 20 minutes- 1 hr 48 minutes
Nana76 [90]

You first convert everything to minutes

3hrs= 60x3=180mins

1hr= 60x1=60mins

then you add 20 to 180

200

and you also add 48 to 60

104

200-104=

96

Then you convert to hrs and mins

96-60=36

One bag of Roland fertilizer covers 2346 square feet of lawn. How many total bags of fertilizer must be purchased to cover a law
Ivenika [448]
If I did my math correct it should be 47. If you take 284x386 you get 109,624 (that should be the area in square feet) then take 109,624 and divide it into 2346 and you get 46.7280477408. In order to cover it you should round up to 47 bags.

What is the area of this polygon?<br><br> Enter your answer in the box.<br><br> units²
leva [86]

Answer:

45 sq. units

Step-by-step explanation:

We can draw a segment from F to S, splitting this figure into a rectangle and a triangle.

The area of a rectangle is given by the formula A=lw, where l is the length and w is the width.

The width of this figure is the distance of FW; this is 2.  The length of this figure is the distance of WC; this is 9.  This makes the area of the rectangle A=2(9) = 18 sq. units.

The area of a triangle is given by the formula A=1/2(b)(h), where b is the base and h is the height.

The base of the triangle is given by the distance of FS; this is 9.  The height of the triangle is given from N to segment FS; this is 6.  This makes the area of the triangle A=1/2(6)(9) = 27 sq. units.

This makes the total area 18+27 = 45 sq. units.
