Question

(-3 xy ³)²×0,4x5y‐²​

Answer 1

Ответ:3,6х⁷у⁴

Решение:

(-3 xy ³)²×0,4x5y⁻²=9х²у³ˣ²  ×0,4x⁵у⁻²=9×0,4 х²⁺⁵у⁶⁻²=3,6х⁷у⁴

Answer 2

It seems like you've provided a mathematical expression that needs to be simplified. Let's break it down step by step:

The expression is: (-3xy³)² × 0.4x^5y^(-2)

1. Start by squaring the term inside the parentheses: (-3xy³)² = 9x²y⁶

2. Next, multiply this squared term by 0.4x^5y^(-2):

   9x²y⁶ * 0.4x^5y^(-2)

3. When multiplying variables with the same base (in this case, x and y), you add their exponents:

   9 * 0.4 * x^(2 + 5) * y^(6 - 2) 3.6x^7y^4

So, the simplified expression is 3.6x^7y^4.
