Answer:
3
Step-by-step explanation:
All factorials 5 and above are evenly divisible by 15, so have no remainder. Thus, you are interested in ...
mod(1! +2! +3! +4!, 15) = mod(1 +2 +6 +24, 15)
= mod(33, 15) = 3
The remainder is 3.
Hello! :)

Use the exponential rule:

Use this property in this scenario:

Simplify:

Sum of an irrational number and a rational number is always irrational. Take for example 1/2 +

. Clearly, 1/2 is rational and its decimal expansion is equal to 0.5, while

is irrational and has a non-repeating, non-terminating decimal expansion. When you add the two, you are obviously going to get a non-repeating, non-terminating decimal expansion, hence the sum is irrational.
