ответ:Решение:
$\frac{1}{4}\cdot\left(1\frac{1}{2}+\frac{1}{8}\right)^2+1.56=\frac{1}{4}\cdot\left(1\frac{5}{8}\right)^2+1.56=\frac{1}{4}\cdot\frac{169}{64}+1.56=\frac{169}{256}+1.56=2\frac{1409}{6400}=2\frac{1409}{6400}=2.22015625$
1 1 2 + 1 8 = 1 + 1 2 + 1 8 = 1 + 1 · 4 2 · 4 + 1 · 1 8 · 1 = 1 + 4 8 + 1 8 = 1 + 4 + 1 8 = 1 + 5 8 = 1 5 8 = 1.625
(1 5 8 )2 = 169 64
1 4 × 169 64 = 1·169 4·64 = 169 256 = 0.66015625
169 256 + 1.56 = 169 256 + 1 56 100 = 1 + 169 256 + 56 100 = 1 + 169 · 25 256 · 25 + 56 · 64 100 · 64 = 1 + 4225 6400 + 3584 6400 = 1 + 4225 + 3584 6400 = 1 + 7809 6400 = 1 +
