Numbers like 10, 100, 1,000, and so on are called exponents.
Exponentiation is a mathematical process that involves the base b and the exponent or power n. It is represented by the symbol bn and is spoken as "b raised to the power of n."
Numbers starting with a 1 and followed by only 0s (such as 10, 100, 1,000,10,000, and so forth) are called powers of ten, and they're easy to represent as "exponents". Powers of ten are the result of multiplying 10 times itself any number of times.
Exponents are also used to represent numbers in the form of scientific notations. Scientific notations are used to represent extremely large numbers or extremely small numbers.
Therefore, the numbers like 10, 100, 1,000, and so on are called exponents.

Step-by-step explanation:
We have been given that one winter day,the temperature ranged from a high 20°F to a low -25°F.
To find the degrees by which temperature dropped, we will find difference between the final temperature and initial temperature.
Since our difference is negative, therefore, the temperature dropped 45 degrees Fahrenheit.

Unit rate is a rate that has 1 as denominator.
Given the rate: 6 inches / 12 hours, we have to divide numerator and denominator by 12 to transform the denominator in 1, as follows:
0.5 inches/hour
Answer:
so if all of the awnsers are whole numbers it is going to be 12/12
