Five fives challenge

Question

Hi,

This is not a question but a challenge that stimulates creativity and teaches mental arithmetic in a fun way.

Some of the numbers, like 39 require a lot of thinking.....

Using only five numerals 5 (no less and no more) express all positive integers from 0 to 50 using only the four arithmetic operations, square root, fifth root, factorial and a decimal point. For example:

0 = (5-5)/(5+5+5)

1 = (5/5) + (5-5)/5

2 = (5+5)/5 + (5-5)

3 = [(5 x 5) + 5]/ (5+5) = (5+5)/5 + 5/5

Good luck and please post your answers

etc

Answer 1

I like your system.

As for 39; multiply by 40 then subtract the multiple.
