Question

What is the leading coefficient that would be used for the scientific notation of this number? (0.0000201 )

A) (2.01 × 10⁻5 )
B) (20.1 × 10⁻6 )
C) (201 × 10⁻7 )
D) (2.01 × 10⁻6 )

Answer 1

The leading coefficient that would be used for the scientific notation of the number 0.0000201 is (2.01 × 10⁻⁵).

Step-by-step explanation:

The leading coefficient that would be used for the scientific notation of the number 0.0000201 is (2.01 × 10⁻⁵).

Scientific notation is a way to express very large or very small numbers using powers of 10. The leading coefficient is the digit or digits in front of the decimal point. In this case, the leading coefficient is 2.01. Since the original number is already in scientific notation with the decimal point after the 2, we don't need to make any adjustments to the coefficient or exponent to express it in scientific notation.

Therefore, the correct answer is option (2.01 × 10⁻⁵).
