Answer 1

Resposta:

Escreva em notação científica:

a) 0,0000012 =1,2 x 10^-6

b) 0,234234 =2,34234 x 10^-1

c) 0,0000000223=2,23 x 10^-8

d) 0,0204 =2,04 x 10^-2

e) 23.000.000 =2,3 x 10^+7

f) 1.325.000 =1,325 x 10^+6

g) 8.532.000.000 =8,532 x 10^+9

h) 12.000.000.000.000 =​1,2 x 10^+13

explanation:

The scientific notation of a number is a number between 1.0 and 9.99999 multiplied by the base of 10 elevators to an exponent.

Scientific notation is very useful for making very large or very small numbers more easily readable and therefore understandable.

As an example, let's take the number 0.0000000000000000000056. This is not easy to read. This same number in scientific notation is 5.6 x 10²¹. It is now much easier for scientists to read this number. Now it's easier to have quantified terms. Let us now take a very large number, such as 23,000,000,000,000,0000. This number in scientific notation is 2.3 x 10 ¹⁶. This, again, is much easier to read and understand.

This is why scientific notation is so important and why it is used and why you should know how to convert or have a converter available to make numbers in scientific notation form.

To be in scientific form, the number that will be multiplied by a base 10 number and an exponent must be between 1.0 and 9.99. This is the first rule of scientific notation. Once the number is between 1 and 10, then multiply by base 10. The exponent that base 10 is determined how big or small the number is. And if The exponent is negative, then the final value will be a number less than 1. If the exponent is 0, the number retains its original value. If the exponent is Positive, then the number will be greater than 10.
