Correct Answer: 0.8125


Solution : Given:
$\frac{(0.25)^4+2×(0.25)^2+1–(0.25)^2}{(0.25)^2+0.25+1}$
= $\frac{((0.25)^2+1)^2–(0.25)^2}{(0.25)^2+0.25+1}$
= $\frac{((0.25)^2+1+0.25)((0.25)^2+1–0.25)}{(0.25)^2+0.25+1}$
= $\frac{((0.25)^2+0.25+1)((0.25)^2+1–0.25)}{(0.25)^2+0.25+1}$
= $0.25^2 + 1 - 0.25$
= $0.0625 + 0.75$
= $0.8125$
Hence, the correct answer is 0.8125.
