add d to 5, raise the result to the 9th power, then subtract what you have from 2

add d to 5, raise the result to the 9th power, then subtract what you have from 2

Add d to 5:
d + 5

Raise the result to the 9th power means we raise (d + 5) to the 9th power using an exponent:
(d + 5)^9

the subtract what we have (the result) from 2:
2 - (d + 5)^9
