What is the only number that cannot be written in scientific notation? explain

Single digit natural number can't be write in scientific notation.

We write very large and long positive number into scientific notation because it's easy to read.

We can't write negative number into scientific notation.

Step-by-step explanation:

Single digit natural numbers are 1,2,3,4,5,6,7,8,9

Scientific Notation:

where,

k is between 1 to 9 , i,e

n is any integers.

Example: Write in scientific notation

1) 5869742000

Scientific Notation:

2) 0.000000849

Scientific Notation:

the figures below are made out of circles, semicircles, quarter … find the area and the perimeter of each figure and give your answers as a completely simplified exact value in terms of π (no approximations). remember that we'll also have to cut whatever areas we get in half, since we're only dealing im pretty sure that is the right answer

step-by-step explanation:

there are 70 more legs than eyes at the dog show (196 – 126 = 70). dogs have two more legs than eyes, and humans have the same number of legs as eyes. thus 70 is twice the number of dogs at the show, so the number of dogs is half of 70, which is 35. to get the number of humans, subtract 35 from 63: 63 – 35 = 28.
