The exponent of 3 is a giveaway that the solution will have to devolve to 2^3 at

some point. So the assumption would be that the expression that results in the "2" would be in parentheses: (2)^3. Then it's as simple as trying to figure out how to use 1, 2, 3, + and - to come up with a result of "2". The answer to that is 3-2+1. Thus, (3-2+1)^3=8.

Math Question: using only the following numbers and symbols, write an expression

Do you have to use all of them?

Yes.

exponent of 3?

Baron

Yes. Meaning you have to have either 1^3 or 2^3 or 3^3

If you don’t have to use them all, then 2 exponent of 3 = 8

Except you have to use the + and - and (). This is my daughter’s sixth grade

(3-2+1)^3 = 8

Dang it! I shouldn't have spent so long double checking my math 🤔😉😅

Being an actuary has its perks. Didn’t think it’d be CB math problems but alas

I kept thinking, “this shouldn’t be that hard….” And apparently it wasn’t. Guess

yeah, I worked backward from that point as well.

I prefer (3+1-2)^3

This was my solution. My kid is in the same class as BYU-Ite’s kid and we were

Don’t know why I thought you said equal to zero, nothing to see here

(3+1-2)^3=8. Thanks. That was a fun 30 seconds...on to nerdle

(3+1-2)^3

Alternative answer that doesn't cube the 2 — (3^3)-2+1=8

unctoothman

9/23/22 8:11am

3^3 would be 27

PHXSUNS31

9/23/22 8:19am

Right. So 27, then take away the 2 (i.e. make 27 into 7) then add 1. Equals 8. Easy.

unctoothman

9/23/22 8:39am

Genius

PHXSUNS31

But it's supposed to be a math expression, not a meth expression.
