Question

1. each planets distance from earth varies. place the planets in order from least to greatest.

mercury: $9.17\times10^{5}$
saturn: $1.25\times10^{7}$
neptune: $4.3\times10^{6}$
jupiter: $6.2444\times10^{5}$
1.
2.
3.
4.

Explanation:

Step1: Compare exponents

We have numbers in scientific - notation. First, compare the exponents of 10. Mercury: $9.17\times10^{5}$, Saturn: $1.25\times10^{7}$, Neptune: $4.3\times10^{6}$, Jupiter: $6.2444\times10^{5}$. The exponents are 5, 7, 6, 5. Smaller exponents mean smaller numbers when the coefficients are positive.

Step2: Compare numbers with same exponents

For Mercury ($9.17\times10^{5}$) and Jupiter ($6.2444\times10^{5}$), since the exponents are the same, we compare the coefficients. $6.2444<9.17$.

Step3: Order the numbers

The order from least to greatest is: Jupiter ($6.2444\times10^{5}$), Mercury ($9.17\times10^{5}$), Neptune ($4.3\times10^{6}$), Saturn ($1.25\times10^{7}$).

Answer:

1. Jupiter: $6.2444\times10^{5}$
2. Mercury: $9.17\times10^{5}$
3. Neptune: $4.3\times10^{6}$
4. Saturn: $1.25\times10^{7}$
