Given:
Side length of square = 2 in
To find:
The area of the square
Solution:
Area of the square:
Area = side × side
= 2 in × 2 in
Area = 4 in²
Therefore, the area of the square is 4 inches².
Exact numbers are numbers are exact (and therefore have an unlimited number of significant figures)
<h3>What are exact numbers?</h3>
Exact numbers can be defined as numbers known with complete certainty.
These numbers have zero uncertainty and have infinite values.
Some examples of exact numbers are:
- counted numbers of objects or certain unit conversions such as 3 feet in 1 yard, exactly 12 eggs in a dozen
We can see that exact numbers have infinite values and thus have unlimited number of significant figures.
Thus, exact numbers are numbers are exact (and therefore have an unlimited number of significant figures)

Answer:
67.938 =
(6 * 10^1) + (7 * 10^0) + (9 * 10^-1) + (3 * 10^-2) + (8 * 10^-3)
Step-by-step explanation:
Here, we want to write the given number in expanded form
Mathematically that will be ;
60 + 7 + 0.9 + 0.03 + 0.008
Using the power of 10, that will be;
(6 * 10^1) + (7 * 10^0) + (9 * 10^-1) + (3 * 10^-2) + (8 * 10^-3)
Answer:3
Step-by-step explanation:
Answer:
Below are explanations!
Step-by-step explanation:
6) 5^4/5^2 means the ^4 and ^2 needs to subtract from the 5s. This results in 5^2, which equals 25.
7) The 9 as the denominator will cross with the first nine above. This leaves as follows: 9^3 x 9^2 x 9^6 (I don't know if it is a 6 or 0). You may solve from there. Just add all the exponents up.
8)^-6 will be multiplied by ^6, which is ^-36. Therefore, the answer is 5^-36.
