Question

M-9/6m : m(2)-81/18m(2)​

Answer 1

Я так понял, что в скобочках была степень. Тогда ответ:

$\frac{2Mm-3-9m^3}{2m}$

Answer 2

To simplify the expression M-9/6m : m(2)-81/18m(2), let's break it down step-by-step.

Step 1: Simplify the numerator and denominator of each term separately.

Numerator 1: M - 9 Numerator 2: m(2) = m * 2 = 2m

Denominator 1: 6m Denominator 2: 18m(2) = 18 * m * 2 = 36m

Step 2: Combine the simplified terms.

The expression becomes:

(M - 9)/(6m) : 2m/(36m)

Step 3: Invert the second fraction (the denominator becomes the numerator, and vice versa) and change the division to multiplication.

(M - 9)/(6m) * (36m)/(2m)

Step 4: Cancel out common factors.

In the second fraction, we have a common factor of 'm' in the numerator and denominator. Cancel it out:

(M - 9)/(6) * (36)/(2)

Step 5: Further simplify.

(6M - 54) / 6 * 18

Step 6: Cancel the common factor of 6.

M - 9 * 18

Step 7: Finally, multiply:

18M - 162

So, the simplified expression is 18M - 162.
