Math Problem Statement

Simplify the rational expression (2/a + 7/b) / b.

Solution

PIL import Image import pytesseract

Load the image

image_path = "/mnt/data/17331364048390h7gfg1e.jpg" image = Image.open(image_path)

Use OCR to extract text

extracted_text = pytesseract.image_to_string(image) extracted_textThe exercise asks to simplify the given rational expression:

2a+7bb.\frac{\frac{2}{a} + \frac{7}{b}}{b}.

Solution:

  1. Combine the fractions in the numerator (2a+7b\frac{2}{a} + \frac{7}{b}): 2a+7b=2b+7aab.\frac{2}{a} + \frac{7}{b} = \frac{2b + 7a}{ab}.

  2. Substitute this result into the original expression: 2b+7aabb.\frac{\frac{2b + 7a}{ab}}{b}.

  3. Simplify the division by bb (division by bb is equivalent to multiplying by 1b\frac{1}{b}): 2b+7aabb=2b+7aabb.\frac{\frac{2b + 7a}{ab}}{b} = \frac{2b + 7a}{ab \cdot b}.

  4. Simplify the denominator: 2b+7aab2.\frac{2b + 7a}{ab^2}.

Final Answer:

2b+7aab2.\frac{2b + 7a}{ab^2}.
