Is there another part to your question
Answer:
what!!!!!!!!!!!!!!!!!! so only for dudesssssssss
Answer:
(a)
Multiplicative inverse of w will be
(B) As w is same as the product of
So there multiplicative inverse will also be same
Step-by-step explanation:
We have given two complex numbers
and
(a) First we have to find
So
As we know that
So
Multiplicative inverse :
It is that number when multiply with the number which we have have to find the multiplicative inverse gives result as 1
So multiplicative inverse of w will be
Because when we multiply with it gives result as 1
(b) As w is same as the product of
So there multiplicative inverse will also be same
Since they have the same base we can just add all the exponents
-3+ 10= 7
keep the base so the answer is
12^7
Firstly, we'll fix the postions where the women will be. We have forms to do that. So, we'll obtain a row like:
The n+1 spaces represented by the underline positions will receive the men of the row. Then,
Since there is no women sitting together, we must write that . It guarantees that there is at least one man between two consecutive women. We'll do some substitutions:
The equation (i) can be rewritten as:
We obtained a linear problem of non-negative integer solutions in (ii). The number of solutions to this type of problem are known:
[I can write the proof if you want]
Now, we just have to calculate the number of forms to permute the men that are dispposed in the row:
Multiplying all results:
