Question

evaluate the summation for the indicated value of the variable. 1(1!) 2(2!) 3(3!) 4(4!) m(m!); m

Answer 1

The summation for the indicated value of the variable is 23.

What is factorial?

The product of all positive integers less than or equal to n in mathematics is known as the factorial of a non-negative integer, indicated by the symbol n!. Additionally, the factorial of n is equal to the sum of n and the subsequent smaller factorial: For instance, According to the convention for an empty product, the value of 0! is 1.

Here, we have

Given

1(1!) +2(2!) +3(3!) + 4(4!)+......... m(m!)

By applying summation,

For m = 3, it will become,

= 1(1!) +2(2!) +3(3!)

Now we open factorization and we get

= 1(1) +2(2×1) +3(3×2×1)

= 1 + 4 + 18

= 23

Hence, the summation for the indicated value of the variable is 23.
