Question

5 4/9:1/9- 1 3/8*16+(2 1/2 вторая степень):(1/2 третья степень)

Answer 1

Ответ:

31

Пошаговое объяснение:

$\frac{49}{9} *9-\frac{11}{8}*16+(2*\frac{1}{4})+(\frac{1}{2})^3$

$49-11*2+\frac{1}{2}+(\frac{1}{2})^3$

$49-22+(\frac{1}{2})^-2$

$49-22+4=31$

Answer 2

To solve this expression, we need to follow the order of operations, also known as PEMDAS (Parentheses, Exponents, Multiplication and Division, and Addition and Subtraction).

1. First, let's simplify the expression inside the parentheses:

   1 3/8 * 16 = 1 * 16 + 3/8 * 16 = 16 + 6 = 22

2. Next, let's simplify the expression inside the exponent:

   2 1/2 вторая степень = (2.5)² = 6.25

3. Now we can substitute these values into the original expression and simplify further:

   5 4/9:1/9 - 22 + 6.25:(1/2)³ = 5 4/9:1/9 - 22 + 6.25:(1/8) (since (1/2)³ = 1/2 * 1/2 * 1/2 = 1/8) = 5 4/9 * 9 - 22 + 6.25 * 8 (since dividing by a fraction is the same as multiplying by its reciprocal) = 49 - 22 + 50 = 77

Therefore, the value of the expression is 77.
