Answer 1

Answer:

1. -15

2. 16

3. 48

4. 219

5. 65

Step-by-step explanation:

Remember to do PEMDAS: parentheses, exponents, multiplication, division, addition, and subtraction.

1. 7 - 2(2 + 5) - 8 = 7 - 2(7) - 8 = 7 - 14 - 8 = -7 - 8 = -15

2. 15 + 3 - 2(2 - 1) = 15 + 3 - 2(1) = 15 + 3 - 2 = 18 - 2 = 16

3. 3[9 - (2 + 3)]^2 = 3[9 - 5]^2 = 3[4]^2 = 3(16) = 48

4. 225 + (7 - 4)^2 - 15 = 225 + 3^2 - 15 = 225 + 9 - 15 = 234 - 15 = 219

5. 200 - 5(4 - 1)^3 = 200 - 5(3)^3 = 200 - 5(27) = 200 - 135 = 65

Answer 2

Answer:

1. -15

2. 16

3. 48

4. 10

5. 65

Step-by-step explanation:

1. 7 - 2(2+5) - 8

7 - 2(7) - 8

7 - 14 - 8

-7 - 8

-15

2. 15 + 3 - 2(2-1)

15 + 3 - 2(1)

18 - 2

16

3. 3(9 - (2+3))²

3(9 - 5)²

3(4)²

3(16)

48

4. 225 ÷ (7-4)² - 15

225÷(3)² - 15

225 ÷ 9 - 15

25 - 15

10

5. 200 - 5(4-1)³

200 - 5(3)³

200 - 5(27)

200 - 135

65
