just multiply 3.92 * 9.3*10^7

Part a:

or d = 3.92 * (9.3*10^7)

Part b:

d = 3.6456*10^8 miles

d = 364,560,000 miles

In order to convert from au to miles, you just need to look at your conversion factor. So for part a, all you’ll need to do is write 3.92au*(9.3*10^7miles)/1 au.

The unit au will cancel out, as you have “au” in the numerator and “au” in the denominator, so your expression is:

3.92 * (9.3*10^7miles)

(The 1 in the denominator cancelled out).

For part b, all you’ll need to do is punch the equation into a calculator (or solve it by hand if you feel so compelled).

Good luck!
