Question

Write the standard number 0.0003571 in scientific notation.

Answer 1

Hey there!

`\large\boxed{3.571*10^(-4)}`

Scientific notation consists of one number that is at least one and less than ten which is multiplied by 10 with an exponent.

We need to move the decimal place of 0.0003571 4 places to the right to get a number that is more than one and less than ten, so the exponent on the ten will be -4: the 4 because we are moving it 4 places, and the - because we are moving it to the right.

So, the answer is:

`3.571*10^(-4)`

Hope this helps!

Answer 2

3.571 * 10^-4

Explanation:

0.0003571

Scientific notation is a *10^b

where a is a number between 1 and less than 10

We determine b by how many places we have to move the decimal

We need to move the decimal to the right 4 places. Moving it to the right means it is negative

a = 3.571 b = -4

3.571 * 10^-4
