Фото во вложении, решите №8
m m+4 m 1
.......=( ----------- - ----------------- ) * 2⁴(m-1)⁴ = ( ------------ - ------------- ) *2⁴ (m-1)⁴ =
(m-1)² (m-1)(m+4) (m-1)² m-1
m-m+1 2⁴(m-1)⁴
= ---------------- *2⁴ (m-1)⁴ = -------------- = 2⁴(m-1)²= 16(√3+1-1)²=16(√3)²=16*3=48
(m-1)² (m-1)²

m m+4 m 1
.......=( ----------- - ----------------- ) * 2⁴(m-1)⁴ = ( ------------ - ------------- ) *2⁴ (m-1)⁴ =
(m-1)² (m-1)(m+4) (m-1)² m-1
m-m+1 2⁴(m-1)⁴
= ---------------- *2⁴ (m-1)⁴ = -------------- = 2⁴(m-1)²= 16(√3+1-1)²=16(√3)²=16*3=48
(m-1)² (m-1)²
