Question

1,6²:(3 4/13 + 9/13) - 0,3³​

Answer 1

Ответ:

0,613

Пошаговое объяснение:

1) 3 4/13 + 9/13 = 3 13/13 = 4

2) 1,6² : 4 = (1,6 * 1,6) : 4 = 2,56 : 4 = 0,64

3) 0,64 - 0,3³ = 0,64 - (0,3 * 0,3 * 0,3) = 0,64 - 0,027 = 0,613

Answer 2

To solve this mathematical expression, follow the order of operations (PEMDAS/BODMAS):

1. First, simplify inside the parentheses: 3 4/13 + 9/13 = 3 13/13 + 9/13 = 3 + 9/13

2. Now, calculate the exponent: 0.3³ = 0.3 * 0.3 * 0.3 = 0.027

3. Next, perform the division: 1.6² / (3 + 9/13) = 2.56 / (3 + 9/13)

4. Add the fractions in the denominator: 3 + 9/13 = 3 * 13/13 + 9/13 = 39/13 + 9/13 = 48/13

5. Now, divide 2.56 by 48/13: (2.56) / (48/13) = 2.56 * (13/48)

6. Multiply the fractions: 2.56 * (13/48) = (2.56 * 13) / 48 = 33.28 / 48

7. Simplify the fraction by dividing both the numerator and denominator by their greatest common divisor (which is 16): (33.28 / 16) / (48 / 16) = (2.08) / (3)

So, the final result is approximately: 2.08 / 3 ≈ 0.6933
