Ответы на вопрос:
14(1+√31)+(7 - √31)² = 14 + 14√31 + 7² - 2*7*√31 + (√31)² = = 14 + 14√31 + 49 - 14√31 + 31 = (14 + 49 + 31 ) + (14√31 - 14√31)= = 94 (√43 - 5)² + 10(√43 - 0.2) = (√43)² - 2*√43 * 5 + 5² + 10√43 - 2 = = 43 - 10√43 + 25 + 10√43 - 2 = 66 (11 - √17)(11 +√17) = 11² - (√17)² = 121 - 17 = 104 (√2 -√15)² + (√6+√5)² = (√2)² - 2*√2*√15 + (√15)² + (√6)² + 2*√6*√5 +(√5)²= = 2 - 2√30 + 15 + 6 + 2√30 + 5 = 28 №336. 2√3(√12 + 3√5) - √5(6√3 - √20) = 2√36 + 6√15 - 6√15 +√100= = 2*6 + 10 = 12 +10 = 22 √6(0,5√24 - 8√11) - 4√11(√99 -2√6) = = 0,5√144 - 8√66 - 4√1089 + 8√66 = = 0,5 * 12 - 4*33 = 6 - 132 = - 126 (√162 - 10√5)√2 + (5 + √10)² = = √324 - 10√10 + 25 + 10√10 + (√10)² = = 18 + 25 + 10 = 53 (17 - √21)² - 5√3(4√27 - 6,8√7) = = 17² - 2*17*√21 + (√21)² - 20√81 + 34√21 = = 289 - 34√21 + 21 - 20*9 + 34√21 = = 289 + 21 - 180 = 130
14(1+√31)+(7-√31)^2=14 +14 √31 +49 -14√31 +31 = 94 (√43-5)^2+10(√43-0,2)= 43 -10√43 +25 +10√43 -2 = 66 (11-√17)(11+√17)=121 - 17 = 104(√2-√15)^2+(√6+√5)^2=2 - 2√30 +15 +6 +2√30 +5 = 28 №336.2√3(√12+3√5)-√5(6√3-√20)= 2√36 + 6√15 -6√15 +√100= 12 +10 = 22 √6(0,5√24-8√11)-4√11(√99-2√6)=0,5√144 -8√ 66 -4√(99*11) +4√66= =6 -132 = -126(√162-10√5)√2 + (5+√10)^2=√324 - 10√10 +25 +10√10 +10= =18 +25 +10 = 53 (17-√21)^2 - 5√3(4√27-6,8√7)=289 -34√21 +21 - 20√81 + 34√21= =289 +21 -180 = 130
