(15, 96) (35, 216)
Option 1: (41, 250)
Option 2: (18, 102)
Option 3: (29, 180)

Question : What is the simplified value of $(x^{128}+1)(x^{32}+1)(x^{64}+1)(x^{16}+1)(x^{8}+1)(x^{4}+1)(x^{2}+1)(x+1)?$
Option 1: $x^{256}-1$
Option 2: $\frac{x^{128}-1}{x-1}$
Option 3: $\frac{x^{64}-1}{x-1}$
Option 4: $\frac{x^{256}-1}{x-1}$
Correct Answer: $\frac{x^{256}-1}{x-1}$
Solution : Given: $(x^{128}+1)(x^{32}+1)(x^{64}+1)(x^{16}+1)(x^{8}+1)(x^{4}+1)(x^{2}+1)(x+1)$ Multiplying $(x-1)$ in both numerator and denominator, $\frac{(x^{128}+1)(x^{32}+1)(x^{64}+1)(x^{16}+1)(x^{8}+1)(x^{4}+1)(x^{2}+1)(x+1)(x-1)}{(x-1)}$ Using identity: $(a^2-b^2)=(a-b)(a+b)$, = $\frac{(x^{128}+1)(x^{32}+1)(x^{64}+1)(x^{16}+1)(x^{8}+1)(x^{4}+1)(x^{2}+1)(x^2-1)}{(x-1)}$ = $\frac{(x^{128}+1)(x^{32}+1)(x^{64}+1)(x^{16}+1)(x^{8}+1)(x^{4}+1)(x^4-1)}{(x-1)}$ = $\frac{(x^{128}+1)(x^{32}+1)(x^{64}+1)(x^{16}+1)(x^{8}+1)(x^8-1)}{(x-1)}$ = $\frac{(x^{128}+1)(x^{32}+1)(x^{64}+1)(x^{16}+1)(x^{16}-1)}{(x-1)}$ = $\frac{(x^{128}+1)(x^{32}+1)(x^{64}+1)(x^{32}-1)}{(x-1)}$ = $\frac{(x^{128}+1)(x^{64}+1)(x^{64}-1)}{(x-1)}$ = $\frac{(x^{128}+1)(x^{128}-1)}{(x-1)}$ = $\frac{(x^{256}-1)}{(x-1)}$ Hence, the correct answer is $\frac{(x^{256}-1)}{(x-1)}$.
