### Can U solve this?

Make 100 using the numbers 400, 200, 50 and 2.
Use the operations + - * / 2 (square) 3 (cube).

Hi;

Welcome to the forum.

In mathematics, you don't understand things. You just get used to them.
I have the result, but I do not yet know how to get it.
All physicists, and a good many quite respectable mathematicians are contemptuous about proof.

Bobbym and anonimnystefy, you are both correct!
Now, second equation using PEMDAS:
Make 75 using the numbers 5 5 3.
Use the operations + - * / 2 3.

Hi julianthemath;

I missed that you only wanted the operations of factorial and 2 and 3.
