Question

Scientific notation of 0.00000000239 and standard form of 5.72 X 106 .​

Answer 1

Answer:

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 0.00000000239 into scientific notation, follow these steps:

Move the decimal 9 times to right in the number so that the resulting number, m = 2.39, 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 = -9

Write in the scientific notation form, m × 10n

= 2.39 × 10-9

Therefore, the decimal number 0.00000000239 written in scientific notation is 2.39 × 10-9 and it has 3 significant figures.
