There is a rule of Algebra, that says
(a^m)[x] (a^n) = a^(m+n)
a is the base of the power, n, and m are the exponents. As you can see, multiplying two powers of the same base is equal to the power of the (common) base with the sum of the exponents.
If that is what you had in mind, the calculator uses the rule correctly and no intervention from you is necessary.
If you enter (2^4)[x](2^6), the calculator will give 1024, which is 2^10.
I may be wrong, but what you call add exponents refers really to performing addition where addends (the terms you add) are arbitrary powers, such as
2^7 + (5.5^3) - (1/3)^4
Once you enter a power term, the calculator calculates it and the result is now just a number. It can be added, subtracted, multiplied
For the exemple above
2 [Y to the x] 7 + (5.5)[Y to the x] 3 -(1/3) [Y to the x] 4 [=] yields 294.3626543
For the cube of 5.5 you can use the key combination [2nd][X^3]
Hope it helps.
