Answer 2

Ответ:

1) (64+27)+9=91+9=100

2)64+(120-40)=64+80=144

3)125×(145-56-89)=125×0=0

Answer 3

Let's solve each expression step by step:

1. (8² + 3³) + 9 First, calculate the powers and addition inside the parentheses: (64 + 27) + 9 Now, perform the addition inside the parentheses: 91 + 9 Finally, add the remaining numbers: 91 + 9 = 100

2. 4³ + (120 − 40) Calculate the cube of 4: 4³ = 4 * 4 * 4 = 64 Now, perform the subtraction inside the parentheses: 64 + (120 - 40) Calculate the subtraction inside the parentheses: 64 + 80 Finally, add the remaining numbers: 64 + 80 = 144

3. 5³ × (145 − 56 + (−89)) First, perform the addition inside the inner parentheses: 5³ × (145 - 56 - 89) Now, calculate the subtraction inside the parentheses: 5³ × (145 - 145) After the subtraction, we are left with: 5³ × 0 = 0

So, the results are:

1. (8² + 3³) + 9 = 100
2. 4³ + (120 − 40) = 144
3. 5³ × (145 − 56 + (−89)) = 0
