Question

Calcule:

1)3x – 6 – 2x

2) 5 . 4x²

3)21x³ : 3x

4)10x . 10y . 10x³

5) 35x : 5x4

6) 8y² . 7y–7​

Answer 1

Resposta:

1)x-6

2)5.16x²

x=80

3)9261x³:3

x=3087

4)10x.10x.1000x³

x=100×1000

x=100000

5)35x:20

x=1,75

6)64y².0

y=64

Answer 2

꧁Hello, how are you?꧂

$1 ) \: \: 3x - 6 - 2x \\ (3 - 2)x \\ 1x \\ x \\ x - 6$

$2) \: \: 5 \times 4x {}^{2} \\ 20x {}^{2}$

$3) \: \: 21x {}^{3} \div 3x \\ 7x {}^{3} \times x \\ 7x {}^{3} \times x {}^{1} \\ 7x {}^{ 3 + 1} \\ 7x {}^{4}$

$4) \: \: 10x \times 10y \times 10x {}^{3} \\ 1000xyx {}^{3} \\ 1000x {}^{1} yx {}^{ 3} \\ 1000x {}^{1 + 3} y \\ 1000x {}^{4} y$

$5) \: \: 35x \div 5x4 \\ 7x \times x \times 4 \\ 28x \times x \\ 28x {}^{1} \times x \\ 28x {}^{1} \times {}^{} x {}^{1} \\ 28x {}^{1 + 1} \\ 28x {}^{2}$

$6) \: \: 8y {}^{2} \times 7y - 7 \\ 56y {}^{2} \times y - 7 \\ 56y {}^{3} - 7 \\ 7(8y {}^{3} - 1) \\ 2 {}^{3} y {}^{3} - 1 \\ 2 {}^{3} y {}^{3} - 1 {}^{3} \\ (2y) {}^{3} - 1 {}^{3} \\ (2y - 1) \times ((2y) {}^{2} + 2y \times 1 + 1 {}^{2} ) \\ (2y - 1) \times (4y {}^{2} + 2y \times 1 + 1 {}^{2} ) \\ (2y - 1) \times (4y {}^{2} + 2y + 1 {}^{2} ) \\ (2y - 1) \times (4y {}^{2} + 2y + 1)$

Demorei, mas terminei... ;-;
