Answer:
7
Step-by-step explanation:
Using the definition
n
= 
where n! = n(n - 1)(n - 2)..... 3 × 2 × 1
Then
7
= 
= 
← cancel out the multiples 6 ×5 × 4 × 3 × 2 × 1 , then
7 = 7
To do this without a calculator, I would change: 5.2 × 10^(-2) to ... 52×10^(-3)
--> then multiply the whole numbers 52 × 8 = 416
--> next add the exponents on the tens. -3 + -4 = -7
= 416×10^(-7)
* now they'll want you to move the decimal back to behind the first digit. (just standard convention)
= 4.16×10^(-5)
If you have a calculator you can just use the "EE" button for ×10^power typed in it looks like this :
5.2 EE -2 × 8 EE -4 =
then make sure your calculator is in scientific mode, otherwise you'll be counting decimal spaces
