Final answer:
Given that D equals s to the power of 8, the expression 1 + 2D is equivalent to 1 + 2s^8, which is the option C in standard form.
Step-by-step explanation:
The question at hand is asking us to find an expression that equals 1 + 2D given that D = s^8. Using this information, we can substitute the value of D into the expression. This gives us:
1 + 2D = 1 + 2(s^8) = 1 + 2s^8
The expression in standard form that equals 1 + 2D is thus option C, which is 1 + 2s^8.
