Question

`4+2^3-5xx2=14` Apply parenthese so that the equation is true?

Answer 1

`(4+2^3-5)xx2=14`

Explanation:

I do not know of any analytic approach to a problem of this type.
So "trial and error" it is!

Try `(4+2)^3 = 216`
This will be too great to get to 14

`:. 2^3 =8 -> 4+8-5xx2`

Notice: `4+8-5 = 7`

Then: `7xx2 =14`

Hence, the parentheses should be applied as follows:

`(4+2^3-5)xx2=14`
