My teacher gave me the brain teaser and ive been trying to figure it out can someone she wants me to find 2 answers for it.

write an expression that has a value of 40 using two operations and each of the numbers 1, 2, 3, 4, and 5 exactly once.

more rules for your expression

you can use parentheses or other grouping symbols.
you can make one of your numbers an exponent.
you can use either operation as many times as you like, but you can use each number only one time in the expression.
