Question

scientific notation of 38765434​

Answer 1

Answer:

The answer to this question is 3.8765434 × $10^{7}$

Explanation:

For writing anything in scientific notation we always keep only one digit before the decimal point and all other digits are kept after it. We raise the power of the 10 for the number of digits before which we have inserted the decimal point. Before the decimal point, there needs to be a number less than 9. Therefore the scientific notation of the given number 38765434 is given below:

38765434 = 3.8765434 × $10^{7}$

Answer 2

The correct scientific notation  is 3.8765434 ×$10^{7}$

Explanation:

• In scientific notation we always keep only one digit to the right, before the decimal point and all other digits are placed after the decimal i.e here only the digit three (3) is placed before the decimal.
• The number is raised to the power of $10^{n}$ for $n$ number of digits which we have placed after the decimal point. In this case the number of digits after the decimal point is 7 i.e (.8765434). Therfore, $n$ =7 and the number is raised to $10^{7}$.

• Before the decimal point, the number is always supposed to be ≤ 9. Thus, the scientific notation of the number 38765434 is:

        $38765434 = 3.8765434$×$10^{7}$
