Answer 1

Answer:

A

Step-by-step explanation:

Positive numbers in scientific notation (1 digit left of the decimal point) can be ordered by their exponents. Hence a number with a -6 exponent is smaller than a number with a -2 exponent.

Numbers with the same exponent can be ordered by their mantissa. 6 is less than 8.1.

The list that has the numbers in order least to greatest is the first one.

In order to find the answer you need to convert each notation into standard form then order them into least to greatest.

Therefore your answer is option A "1.94 × 10^-5, 1.25 × 10^-2, 6 × 10^4, and 8.1 × 10^4."

Hope this helps!
