А3. (-2а⁴ × b^9)⁴ = (-2)⁴ × (a⁴)⁴ × (b^9)⁴ = 16a^16 × b^36
Ответ: 2) 16а^16 × b^36
A4. (1/4) × ab² × (2a³b⁴)³ = (ab²)/4 × 2³ × (a³)³ × (b⁴)³ = (ab²)/4 × 8a^9 × b¹² = (8/4) × a^(1+9) = b^(2+12) = 2a^10 × b¹⁴
Ответ: 4) 2а^10 × b¹⁴
B1. Если m = -1/2 ; n = -1 , то -32m³n² = -32 × (-1/2)³ × (-1)² = -32 × (-1/8) × 1 = 32/8 = 4
Ответ: 4
B2. y = x³ ; P(-1/2 ; b)
y = (-1/2)³
y = -1/8 => P(-1/2 ; -1/8) => b = -1/8 = -0,125
Ответ: -0,125
