$\large\blue{\textsf{✩ Your Answer ✓ }}$

To convert 0.00000157 into scientific notation, follow these steps:

• Move the decimal 6 times to right in the number so that the resulting number, m = 1.57, 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 = -6
• Write in the scientific notation form, m × 10n = 1.57 × 10-6

Therefore, the decimal number 0.00000157 written in scientific notation is 1.57 × 10-6 and it has 3 significant figures.
