А) 5√3 + √48 - √300 = 5√3 + √16 * √3 - √100 * √3 = 5√3 + 4√3 - 10√3 = -√3
б) 5√2 - √32 + 2√50 = 5√2 - √16 * √2 + 2*√25*√2 = 5√2 - 4√2 + 10√2 = 11√2
в) (√3+√2)^2 + √24 - 5 = 3 + 2√6 + 2 + √4*√6 - 5 = 5 + 2√6 + 2√6 - 5 = 4√6
Sin(73π/24)*sin(37π/24)*sin(37π/12)=sin(3π+π/24)sin(π+13π/24)sin(3π+π/12)=
-sinπ/24*(-sin13π/24)*(-sinπ/12)=-1/2(cos(13π/24-π/24)-cos(13π/24+π/24))*
*sinπ/12=-1/2(cosπ/2-cos7π/12)*sinπ/12=1/2cos7π/12*sinπ/12=
=1/4(sin(π/12-7π/12)+sin(π/12+7π/12))=1/4(sin(-π/2)+sin2π/3)=
=1/4*(-1)+1/4*√3/2=-1/4+√3/8
только так никак по другому
