Question

-х3у2+2х3у2-3х3у2 (2ав3): (2а2в)2

Answer 1

1)-2х^3*у^2
2)(2ав^3):(4а^4*в^2)=0,5*а^-3*в

Answer 2

To simplify the given expression, let's break it down step by step:

1. Combine like terms: -х^3у^2 + 2х^3у^2 - 3х^3у^2 = (-1 + 2 - 3)х^3у^2 = -2х^3у^2

2. Simplify the denominator: (2а^3) / (2а^2в)^2 = (2а^3) / (4а^4в^2) = (1/2) * (а^3/а^4в^2) = (1/2) * (1/ав^2)

3. Combine the numerator and denominator: -2х^3у^2 / ((1/2) * (1/ав^2))

To simplify further, we can multiply the fraction by its reciprocal: -2х^3у^2 * (2/1) * (ав^2/1)

This simplifies to: -4х^3у^2 * ав^2

So, the simplified form of the expression is -4х^3у^2 * ав^2.
