Question

There are approximately 45 hundred species of mammals on Earth and 2.8 x 10 to the 4 species of fish. What is the difference in the number of species?
This is SCIENTIFIC NOTATION

Answer 1

45 hundred = 45 * 100 = 4500

2.8 * 10^4 = 28,000

The difference is the result of subtracting the first number from the second number.

28,000 - 4500 = 23,500

The difference is 23,500 = 2.35 * 10^4

Answer 2

Answer:

23500

Step-by-step explanation:

We are given that

Number of species of mammals on earth=approximately 45 hundred=4500

Number of species of fish=$2.8\times 10^4=2.8\times 10000=28000$

We have to find the difference between the number of species of mammals and fish.

In order to find the difference in the number of species we will subtract number of species mammals from the number  of  species of fish.

Difference=28000-4500=23500

Hence, the difference between the number of species of mammals and fish=23500
