Answer 2

Answer:

$3\times10^{-9},7\times 10^{-5},5\times 10^4,8\times10^4$

Step-by-step explanation:

We want to order ; $5\times 10^4,7\times 10^{-5},3\times10^{-9},8\times10^4$ from least to greatest.

Observe that all these numbers are in standard form.

We can order them based on the exponents.

$-9<\:-5<\:4$

Since two numbers have the same exponent of 4, we need to use the multiplier to order the last two(5<8).

From least to greatest we have;

$3\times10^{-9}\:<\:7\times 10^{-5}\:<\:5\times 10^4\:<\:8\times10^4$
