→ 2ⁿ = ? ; {that is: "2" , raised to the "n th" power, equals {<u>what value</u>} ?
___________________________________________
→ Note that "n" is the haploid number, which is:
"15" (value given within this very question).
__________________________________________________
→ So we plug in "15" for "n" ; to obtain the "final value" —
which is the answer.
