Question

Express 0.2345 in standard form​

Answer 1

ANSWER :-

$2.345 * 10^-^1$

STEP BY STEP 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 0.2345 into scientific notation, follow these steps:

• Move the decimal 1 times to right in the number so that the resulting number, m = 2.345, 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 = -1

• Write in the scientific notation form, m × 10n

$=2.345 * 10^-^1$

Therefore, the decimal number 0.2345 written in scientific notation is $2.345 * 10^-^1$ and it has 4 significant figures.
