Hey there!
What I would do to solve this problem is list out all four of the numbers, then place the other three numbers behind it, like so:
71
73
79
17
13
19
37
31
39
97
91
93
These are all of your possible combinations without any repeats. There's a total of 12 possible combos.
Hope this helped you out! :-)

Any number that we can write as a decimal number between 1.0 and 10.0, multiplied by a power of 10, is said to be in Scientific Notation. Some authors consider standard form and scientific form as the same, but others state that standard form is the common form of expressing numbers, i.e., a sequence of digits, separated by thousands by a comma, and separated from the decimal part by a dot.
We'll give here both answers.
We have to calculate:

Since the numbers don't have the same exponent, we must make them equal. Let's make the second number have an exponent of 5, by dividing by 10:


Now we add:

It's correctly expressed in scientific notation. Now to convert to 'standard form', multiply by
:
