Work: Calculate the value of equation ((-sqrt(21)-sqrt(7))/4)^2+((sqrt(7)-sqrt(21))/4)^2 .
Question type: Mathematical calculation
Solution:
((-sqrt(21)-sqrt(7))/4)^2+((sqrt(7)-sqrt(21))/4)^2
=((-sqrt21-sqrt(7))/4)^2+((sqrt(7)-sqrt(21))/4)^2
=((-sqrt21-sqrt7)/4)^2+((sqrt(7)-sqrt(21))/4)^2
=((-7.228327)/4)^2+((sqrt(7)-sqrt(21))/4)^2
=-1.807082^2+((sqrt(7)-sqrt(21))/4)^2
=-1.807082^2+((sqrt7-sqrt(21))/4)^2
=-1.807082^2+((sqrt7-sqrt21)/4)^2
=-1.807082^2+((-1.936825)/4)^2
=-1.807082^2+(-0.484206)^2
=3.265545354724+-0.484206^2
=3.265545354724+0.234455450436
=3.500001
Answer:((-sqrt(21)-sqrt(7))/4)^2+((sqrt(7)-sqrt(21))/4)^2=3.500001
