number of elements of order n in Zn Z15xZ5 direct product of groups

[@abhishekrawat6914]

Sir ye jo 1000 groups ke mcq hai kya ye csir net ke liye enough hai

[@SantoshiFamily]

Yes

[@sanjana5866]

amazing video......"if d is a poisitive divisors of n ,then the no of elements of order d in cyclic group of order n is phi(d)" this theorem is applicable on Z because it is cyclic then in case of U,S6 it wiil apply???

[@iitjammathematics]

Not applicable

[@samuelsabeng8930]

What will fhi(9) be sir, want to know.

[@SantoshiFamily]

6

[@user-wh7xl5uz8e]

3² -3¹ =6

[@samuelsabeng8930]

Good sir but am still having troubles how fhi(5)=4

[@SantoshiFamily]

There is a formula to find phi(n),

[@user-wh7xl5uz8e]

5¹ -1

[@sreesaivjm8750]

Also (1,5) is not an element in this group, is it?

[@iitjammathematics]

(1, 5) is not an element, but it's the combination of orders

How to find pi(d)=4

[@SantoshiFamily]

Absolutely right

Muze nhi lgta

[@SantoshiFamily]

Thanks for your feedback

[@sreesaivjm8750]

How(5,5) is possible

[@iitjammathematics]

It is not element, it's the possible order such that lcm we can get 5
