I wonder if we can say "two to the three" to indicate 2 to the 3rd power.
Here are my attempts to search on Google for it:
And "two to the third" seems also OK:
Which one do you usually use?
There are three ways to express your phrase:
Two to the third power.
Two to the third.
Two to the power three.
I would always describe that in words as
2 to the 3rd (power)
I would never say
Two to the Three
although I might say
Two to the power of three.
And as a person who majored in physics in college, and has been a software developer for several decades, I have had occasion to discuss raising number to powers many many times. I have never heard a native speaker who knows math say "Two to the three". When the exponent is not a whole number and does not nicely form an ordinal (like first, second, third, fourth) I would say
Two to the power of four point three
E to the X
E to the power of X
