Question

Вычислите: а)4²×33; б) 7+5²; в) (4+3)³; г) 7²+5²; д) (5+7)²; е) (9-6)⁴; ж) (40:8)³+24; з) (9²-5²)×5-35.​

Answer 1

${4}^{2} \times 33 = 16 \times 33 = 528 \\ 7 + 5 {}^{2} = 7 + 25 = 32 \\ (4 + 3) {}^{3} = 7 {}^{3} = 343 \\ 7 {}^{2} + 5 {}^{2} = 49 + 25 = 74 \\ (5 + 7) {}^{2} = 12 {}^{2} = 144 \\ (9 - 6) {}^{4} = 3 {}^{4} = 81 \\ (40 \div 8) {}^{3} + 24 = 5 {}^{3} + 24 = 125 + 24 = 149 \\ (9 {}^{2} - 5 {}^{2} ) \times 5 - 35 = (9 - 5)(9 + 5) \times 5 - 35 = 4 \times 14 \times 5 - 35 = 280 - 35 = 245$

Answer 2

а) 4² × 33 = 16 × 33 = 528 б) 7 + 5² = 7 + 25 = 32 в) (4 + 3)³ = 7³ = 343 г) 7² + 5² = 49 + 25 = 74 д) (5 + 7)² = 12² = 144 е) (9 - 6)⁴ = 3⁴ = 81 ж) (40 ÷ 8)³ + 24 = 5³ + 24 = 125 + 24 = 149 з) (9² - 5²) × 5 - 35 = (81 - 25) × 5 - 35 = 56 × 5 - 35 = 280 - 35 = 245
