a⁴(a⁵+1)
a⁹+a⁴ = ----------- =a⁴ a=-1/3 a⁴=1/3⁴=1
a⁵+1
2. ошибка в учебнике надо 3m³-24
3m³-24 3(m³-2³) 3(m-2)(m²+2m+4)
------------ = ------------- = -------------------------- = 3(m²+2m+4)
3m-6 3(m-2) m-2 m=-4 3(16-8+4)=36
3. b¹²+b³ b³(b⁹+1)
------------ = ---------------- = b³ b=-0.5 -0.5³= -0.125
b⁹+1 b⁹+1
4m²-4m+1 4(m-0.5)²
4. -------------------- = -------------- = m-0.5 m=6 m-0.5=6-0.5=5.5
4m-2 4(m-0.5)
