Question

1) 3x+2/4x-y + 2x-1/y-4x2) (m-2n) : (2n-m)^2/5/ - это линия деления​

Answer 1

Объяснение:

(3х+2)/(4х-у) +(2х-1)/(у-4х)=(3х+2-2х+1)/(4х-у)=(х+3)/(4х-у)

(m-2n)÷(2n-m)^(2/5)=-(2n-m)÷(2n-m)^(2/5)=-(2n-m)^(3/5)=(m-2n)^(3/5)

Answer 2

To clarify the expression, it's essential to use proper parentheses to avoid ambiguity. Let's rewrite the expression using correct grouping:

1. (3x + 2) / (4x - y) + (2x - 1) / (y - 4x)

2. (m - 2n) : ((2n - m)^2 / 5)

Now, let's address each expression separately:

1. (3x + 2) / (4x - y) + (2x - 1) / (y - 4x)

To simplify this expression, we need a common denominator for the fractions. The common denominator is (4x - y)(y - 4x). So, the expression becomes:

[(3x + 2)(y - 4x) + (2x - 1)(4x - y)] / [(4x - y)(y - 4x)]

Expanding the numerators:

[3xy - 12x^2 + 2y - 8x + 8x^2 - y] / [(4x - y)(y - 4x)]

Combining like terms:

[3xy - 4x^2 + 2y - y] / [(4x - y)(y - 4x)]

Simplifying further:

[3xy - 4x^2 + y] / [(4x - y)(y - 4x)]

So, the simplified expression is (3xy - 4x^2 + y) / [(4x - y)(y - 4x)].

2. (m - 2n) : ((2n - m)^2 / 5)

To divide by a fraction, we can multiply by its reciprocal (invert and multiply). So, the expression becomes:

(m - 2n) * (5 / (2n - m)^2)

The expression is now simplified and cannot be further reduced without additional information about the values of 'm' and 'n'.
