Write 0.000000093425 in Scientific Notation with 4 significant figures.

Romashka-Z-Leto [24]

<u>Answer:</u> The given number in scientific notation is $9.342\times 10^{-8}$

<u>Explanation:</u>

Scientific notation is the notation where a number is expressed in the decimal form. This means that the number is always written in the power of 10 form. The numerical digit lies between 0.1.... to 9.9.....

If the decimal is shifting to right side, the power of 10 is negative and if the decimal is shifting to left side, the power of 10 is positive.

We are given:

A number having value = 0.000000093425

Converting this into scientific notation, we get:

$\Rightarrow 0.000000093425=9.342\times 10^{-8}$
