Simplifying Rational Expressions

<p>Для решения данной задачи необходимо упростить рациональное выражение, содержащееся в восьмом номере:</p> <p>\[ \frac{a-1}{2} + \frac{3a-1}{4} - \frac{5a-1}{6} \]</p> <p>Приведём дроби к общему знаменателю, который будет равен 12:</p> <p>\[ \frac{6(a-1)}{12} + \frac{3(3a-1)}{12} - \frac{2(5a-1)}{12} \]</p> <p>Раскроем скобки в числителях:</p> <p>\[ \frac{6a - 6}{12} + \frac{9a - 3}{12} - \frac{10a - 2}{12} \]</p> <p>Теперь сложим дроби, объединив числители:</p> <p>\[ \frac{6a - 6 + 9a - 3 - 10a + 2}{12} \]</p> <p>Произведём сложение и вычитание чисел в числителе:</p> <p>\[ \frac{6a + 9a - 10a - 6 - 3 + 2}{12} \]</p> <p>\[ \frac{5a - 7}{12} \]</p> <p>Итак, упрощённое рациональное выражение:</p> <p>\[ \frac{5a - 7}{12} \]</p>

Determining the Name of Mathematical Expression

The image contains a mathematical question asking for another name for the expression \( B^{3/9} \). Simplifying \( B^{3/9} \) by dividing both the numerator and the denominator of the exponent by their greatest common divisor, which is 3, we get \( B^{(3÷3)/(9÷3)} = B^{1/3} \). Now let's look at the answer options: A) \( B^2 \) B) \( \sqrt[3]{B} \) C) \( B^9 \) D) \( \sqrt[9]{B} \) The correct answer is B, \( \sqrt[3]{B} \), because an exponent of \( 1/3 \) is equivalent to the cube root of the base, in this case, \( B \).
