Question

Вычислите 7 x ²6/7+ 53/12 : (7/9+9/4) ребят срочно

Answer 1

Ответ:

1/84х(504х²+13356/109)

Answer 2

To solve the given expression, let's break it down step by step: 1. Simplify the expression within the parentheses: - 7/9 + 9/4 = (28 + 81) / (36) = 109 / 36 2. Simplify the expression outside the parentheses: - 7 + (x^2 * 6/7) + 53/12 3. Combine the simplified expressions: - 7 + (x^2 * 6/7) + 53/12 + 109/36 Now, let's simplify further: To add fractions, we need to have a common denominator. In this case, the common denominator is 36. 4. Convert all the fractions to have a denominator of 36: - 7 = 7 * (36/36) = 252/36 - 53/12 = (53 * 3) / (12 * 3) = 159/36 - 109/36 (already in the desired form) 5. Add the fractions: - 252/36 + (x^2 * 6/7) + 159/36 + 109/36 6. Combine the numerators: - (252 + 6x^2 + 159 + 109) / 36 7. Simplify the numerator: - (520 + 6x^2) / 36 Therefore, the simplified expression is **(520 + 6x^2) / 36**. Please note that I have provided a step-by-step solution to the given expression. If you have a specific value for 'x', you can substitute it into the expression to find the final result.
