 Hi Ian, how are you all today? The question says is 3 factorial plus 4 factorial is equal to 7 factorial. We know that factorial is equal to multiplying all the natural numbers from 1 to n. That will be 1 multiplied by 2 multiplied by 3 multiplied by 4 multiplied by n minus 1. That is the number that is before n multiplied by n. Similarly, we will be finding out first of all 3 factorial, then 4 factorial, then we will find out there is sum. And then we will see that whether that sum is equal to 7 factorial or not. So these are the 4 steps which we need to do. Let us find it out. 3 factorial means 1 multiplied by 2 multiplied by 3 that gives us 6, right? 4 factorial means exactly multiplying all natural numbers from 1 to 4 that gives us 24. Now we need to add that is 3 factorial is 6, 4 factorial is 24, 6 plus 24 gives us 30. Now let us see whether this is equal to 7 factorial or not. 7 factorial is multiplying all natural numbers from 1 to 7. And the answer of their multiplication comes out to be 5040. So what we can say in the end, we can say that we find that 3 factorial plus 4 factorial is not equal to 7 factorial. So, final answer is no and the sum of 3 factorial plus 4 factorial was 30, right? So this is our required answer. I hope you enjoyed the session. Do remember, firstly you need to find out 3 factorial, then 4 factorial, 7 factorial, there is sum and then you need to see whether 3 factorial plus 4 factorial is equal to the answer of 7 factorial or not. So, bye for now.
