Question

Quien me puede ayudar con esto?

Answer 1

C) Elimina los símbolos de agrupación y resuelve.

1. (6+5+4)3 = 15*3 = 45

2. (20-15+30-10)5 = 25*5 = 125

3. (7-5)4 + 3(4-2) + (8-2)5 - 2(11-10) = 2*4 + 3*2 + 6*5 - 2*1 = 8+5+30-2 = 41

4. 3(9-2) + 2(5-1)(4+3) + 3(6-4)(8-7) = 3*7 + 2*4*7 + 3*2*1 = 21 + 56 + 6 = 83

5. 6[3+ (5-1)2] = 6(3 + 4*2) = 6*11 = 66

6. 9[(10-4)2 + (30-20)2] = 9(6*2 + 10*2) = 9(12+20)= 9*32 = 288

D) Resuelve las siguientes operaciones

1. -3.2 + (-3.2) + (-3.2) = -9.6

2. 2.5 + (-0.5) + (-1) = 2.5 - 1.5 = 1

3. 2.5 -(-3.7) = 2.5 + 3.7 = 6.2

4. 6.9 - (+3.5) = 3.4

5. (5.8 - 9.7) - (7.2 + 2.5) = -3.9 - 9.7 = -13.6

6. (-12.9 - 4.1) - (-56.3 - 4.9) = -17 - (-61.2) = -17 +61.2 = 44.2

Respuesta:

1. (6+5+4)3 = 15*3 = 45

2. (20-15+30-10)5 = 25*5 = 125

3. (7-5)4 + 3(4-2) + (8-2)5 - 2(11-10) = 2*4 + 3*2 + 6*5 - 2*1 = 8+5+30-2 = 41

4. 3(9-2) + 2(5-1)(4+3) + 3(6-4)(8-7) = 3*7 + 2*4*7 + 3*2*1 = 21 + 56 + 6 = 83

5. 6[3+ (5-1)2] = 6(3 + 4*2) = 6*11 = 66

6. 9[(10-4)2 + (30-20)2] = 9(6*2 + 10*2) = 9(12+20)= 9*32 = 288

D) 1. -3.2 + (-3.2) + (-3.2) = -9.6

2. 2.5 + (-0.5) + (-1) = 2.5 - 1.5 = 1

3. 2.5 -(-3.7) = 2.5 + 3.7 = 6.2

4. 6.9 - (+3.5) = 3.4

5. (5.8 - 9.7) - (7.2 + 2.5) = -3.9 - 9.7 = -13.6

6. (-12.9 - 4.1) - (-56.3 - 4.9) = -17 - (-61.2) = -17 +61.2 = 44.2
