Answer:
Number of permutations = 5040
Step-by-step explanation:
We are given the word 'INNOVATIVE', that has total 10 letters.
Now, we are asked to form words using exactly 4 letters at a time i.e. out of 10 letters we are using 4.
Therefore, the number of permutations that can be formed using 4 letters are = P(10,4)
i.e.
=
=
=
= 10*9*8*7
= 5040
Answer:
<em>LCM</em> =
Step-by-step explanation:
Making factors of
Taking common:
Using <em>factorization</em> method:
Now, Making factors of
Taking common:
Using <em>factorization</em> method:
The underlined parts show the Highest Common Factor(HCF).
i.e. <em>HCF</em> is .
We know the relation between <em>LCM, HCF</em> of the two numbers <em>'p' , 'q'</em> and the <em>numbers</em> themselves as:
Using equations <em>(1)</em> and <em>(2)</em>:
Hence, <em>LCM</em> =
