Question

Which list is in order from least to greatest?

Answer 1

Student005,

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

• $1.94 \times 10^{-5} = .0000194$
• $1.25 \times 10^{-2} = .0125$
• $6 \times 10^{4} = 6000.$
• $8.1 \times 10^{4} = 81000.$

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!

Answer 2

Answer:

The first selection

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.
