Question

One type of insect is 0.0052 meters long. What is the lenght in scientific notation

Answer 1

5.2 ×
`10^(-3)`

Explanation:

a number in scientific notation is expressed as

a ×
`10^(n)`

where 1 ≤ a < 10 and n is an integer

write 0.0052 as a number between 1 and 10, that is 5.2

we have to the move the decimal point 3 places to the left to retain it's value

3 places left means n is - 3

0.0052 = 5.2 ×
`10^(-3)`
