Answer:
2.45 x 10^-2
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 0.0245 into scientific notation, follow these steps:
Step 1) Move the decimal 2 times to right in the number so that the resulting number, m = 2.45, is greater than or equal to 1 but less than 10
Step 2) Since we moved the decimal to the right the exponent n is negative
n = -2
Step 3) Write in the scientific notation form m × 10n
= 2.45 × 10-2
Therefore,
2.45 × 10-2 is the scientific notation form of 0.0245 number and 2.45e-2 is the scientific e-notation form for 0.0245
