First, you can factor out 625 using the 'tree' method or the 'ladder' method.
625
/ \
5 125
/ \
5 25
/ \
5 5
This means you can say that 625=5 to the power of 4
If your problem requires you to use only whole integers with exponents, then that would be the only way.
If not, then you can also do 625=25*5²
Answer:
Total cards in a deck=52
Face cards =12
So probability of picking a face card is 12/52=3/13
Step-by-step explanation:
Usually there are 12 face cards in a group, so that would be 12/52 -- but wait! You can simplify, always. check. for. simplifying. possibilities.
Usually in an answer they will include both simplified, and not simplified. Believe it or not, usually they ask for the simplified. Make sure you read carefully.
Here the answer is 21 as the LCM of 14 and 6 is 42 and 42 is exactly divisible by 21.
