Question

Evaluate 3!, 4! and 7! and prove that 3! + 4! #7!​

Answer 1

Ello..✌✌

3 ! = 3 × 2 × 1 = 6

4 ! = 4 × 3 × 2 × 1 = 24

7 ! = 7 × 6 × 5 × 4 × 3 × 2 × 1 = 5040

Now , substituting the values in the LHS ,i.e, 3 ! + 4 !

3 ! + 4 !

= 6 + 24

= 30

Now taking the RHS, 7!

7 ! = 5040

This shows us that, LHS = RHS.

3 ! + 4 ! is not equal to 7! .
