Sqrt[0.04]/0.04=5 n=0.04=1/25 It’s in my head.

You are amazing 🥰🥰

[@John-dp8oh]

I agree. Mental arithmetic. Is he just trying to annoy us with all this convoluted rubbish?

[@sergeyromanov5560]

It must have been special olympics.

I wonder why this easy assignment participated in the French Olympiads... 😂

european maths tends to be stupidly easy

@@sh0gun570 √n / n = √n / (√n • √n) = 1 / √n = 5 --> √n = 1/5 --> n = 1/25
as simple as that... I like cancelling out! 😉

[@officially-hello]

Bro easiest method
just
=square on both sides
=you will get n by n square
= then cut the n square by n
=then you will get 1 / n = 25
=then do reciprocal
=Thus n will equal to 1 by 25

[@darcash1738]

1/sqrtn = 5
1 = 5sqrt(n)
sqrtn = 1/5
n = 1/25

[@davidbrown8763]

When dividing by n, you should state that n is not zero.

[@learnwithchristianekpo6005]

Thankyou

[@Hxcker_47]

Isn't that obvious? :/

[@ElectricGamer_YT]

That's not necessary because n=0 is obviously not a solution.

[@davidbrown8763]

Yes it is obvious. However, in keeping with the modern approach to Mathematics, it is necessary to demonstrate to an examiner that you are aware that dividing by zero is forbidden. It does not take long to write using the "not equal to" sign at the stage of dividing by the unknown.

(√n/n)^2=5^2
n/n^2=25
1/n=25
1=25×n
n=1/25

[@AvikDey-z6y]

{(√n) /n}{(√n) /n}=5
Or n/(n) ^2=5
Or 5(n) ^2=n
Or (n) ^2/n =1/5
Or n=1/5

[@ElectricGamer_YT]

n is not equal to 1/5 what?
