Ответ: 5) 3.2 * 10⁻⁵; 6) 5² = 25; 7) 4; 8) 5
(1,6 ⋅ 10⁻²) ⋅ (2 ⋅ 10⁻³) = 1,6 ⋅ 2 ⋅ 10⁻² ⋅ 10⁻³ = 3,2 ⋅ 10⁻⁵
(a³)^-4 : a⁻¹⁴ = a^(3⋅(-4)) : a⁻¹⁴ = a⁻¹² : a⁻¹⁴ = a^(-12 - (-14)) = a⁻¹²⁺¹⁴ = a²
a² = 5² = 25
\(\frac{16x^4}{y^6} = \frac{16 ⋅ 4^4}{2^6} = \frac{2^4 ⋅ (2^2)^4}{2^6} = \frac{2^4 ⋅ 2^8}{2^6} = \frac{2^{12}}{2^6} = 2^{12-6} = 2^6 = \frac{16 \cdot 256}{64} = \frac{4096}{64} = 64\)
\(\sqrt{a^2 - 4ab + 4b^2} = \sqrt{(a - 2b)^2} = |a - 2b|\)
|3 - 2⋅4| = |3 - 8| = |-5| = 5
