Answer 2

Answer:

0.07829=7.829 × 10-2.

Step-by-step explanation:

All numbers in 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 0.07829 into standard, follow these steps:

1. Move the decimal 2 times to right in the number so that the resulting number, m = 7.829, is greater than or equal to 1 but less than 10

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

n = -2

3. Write in the standard form, m × 10n

= 7.829 × 10-2

Therefore, the decimal number 0.07829 is 7.829 × 10-2 and it has 4 significant figures.
