Question

Rewrite in scientific notation 0.000357

Answer 1

3.57 × 10-4

Explanation:

All numbers in scientific notation or standard form are written in the form

m × 10n, where m is a number between 1 and 10 ( 1 ≤ |m| < 10 ) and the exponent n is a positive or negative integer.

To convert 0.000357 into scientific notation, follow these steps:

Move the decimal 4 times to right in the number so that the resulting number, m = 3.57, is greater than or equal to 1 but less than 10

Since we moved the decimal to the right the exponent n is negative

n = -4

Write in the scientific notation form m × 10n

= 3.57 × 10-4

Therefore,

3.57 × 10-4 is the scientific notation form of 0.000357 number and 3.57e-4 is the scientific e-notation form for All numbers in scientific notation or standard form are written in the form

Answer 2

3.57 x 10^-4

Explanation:

see how many places you have to move the decimal to create a number that is greater than or equal to one, in this case that number would be 3.57

we had to move the decimal four places to get it there

when moving to the left the exponent is negative

when moving to the right the exponent is positive
