Answer:
- <em><u>1. There are infinite 8's</u></em>
- <em><u>2. The estimate is 130.89</u></em>
- <em><u>3. The difference is 0.01</u></em>
<em><u /></em>
Explanation:
There are countless, or infinite, 8's in the answer because the result is a periodic decimal:
The notation used for the periodic decimal numbers is an arc over the number that is repeated. In this case, it would be an arc over the first 8.
I will use a bar just to show how it is, but instead of a bar it should be an arc:
The <em>estimation</em> or approximation to <em>two decimal places</em> requires to drop the 8's since the third one and increase the second 8 to 9 (because the first decimal dropped is greater than or equal to 5).
Thus the estimated value would be 13.89.
The difference is:
- 130.89 - 130.888. . . = 0.0111. . .
- Rounded to 2 decimal places: 0.01
How to check an answer is by plugging the answer you got for x into the equation. do u need to know how to get the answer?
Answer:
1. Well, to cross multiply them you multiply the numerator in the first fraction times the denominator in the second fraction, then you write that number down. ... The reason we cross multiply fractions is to compare them. Cross multiplying fractions tells us if two fractions are equal or which one is greater.
2. Cross multiplying fractions to find a missing numerator or denominator for equivalent fractions works because it is a shortcut for rearranging to isolate the variable.

take the space out
One of the indicies rules is:
![{a}^{ \frac{m}{n} } = \sqrt[n]{ {a}^{m} }](https://tex.z-dn.net/?f=%20%7Ba%7D%5E%7B%20%5Cfrac%7Bm%7D%7Bn%7D%20%7D%20%20%3D%20%20%5Csqrt%5Bn%5D%7B%20%7Ba%7D%5E%7Bm%7D%20%7D%20)
As you "root the bottom and power the top"
Using this format, we can see that 3rdrt8^x can be written as 8^x/3
By the way, 3rdrt8 means 3rd root of 8
