Question

Write in scientific notation: (i) 0.0000725​

Answer 1

Answer:

Given decimal is  0.0000725​

To convert into scientific notation, we have to move the decimal so there is only one non-zero digit to the left of the decimal point. The number of decimal places you move will be the power on 10

• If we move the decimal to the right, the power will be negative.
• If we move the decimal to the left, the power will be positive.

Here we are going to move the decimals to right so the power will be negative.

        ∴  0.0000725​ = 7.25 × 10⁻⁵
