Question

Write 0.00000046 in scientific notation.​
  1. 4.6×108
  2. 4.6×107
  3. 4.6×108
  4. 4.6×107


Solution

The correct option is D 4.6×107

Move the decimal point to the right of 0.00000046 up to 7 places to get 4.6​

Since the number is less than 10 and decimal is moved to the right, so we write a negative exponent to 10.​
0.00000046=4.6×107
This is the required scientific notation.
