what is the units digit of ( 5 ! * 4 ! + 6 ! * 5 ! ) / 2 ?
"( 5 ! * 4 ! + 6 ! * 5 ! ) / 2 = 5 ! ( 4 ! + 6 ! ) / 2 = 120 ( 24 + 720 ) / 2 = ( 120 * 744 ) / 2 = 120 * 372 units digit of the above product will be equal to 0 answer c"
divide(add(multiply(factorial(5), factorial(4)), multiply(factorial(5), factorial(5))), 5)
