Question

(3x⁶-0,3y²)×(3x⁶+0,3y²)​

Answer 1

9х¹²-0.27у⁴

9(х¹²-0.03у⁴)

Answer 2

It looks like you want to multiply two expressions: $3x^6 - 0.3y^2$ and $3x^6 + 0.3y^2$. This is an example of the difference of squares pattern. When you multiply two expressions of the form $(a + b)(a - b)$, you get $a^2 - b^2$. In your case, $a = 3x^6$ and $b = 0.3y^2$.

So, using the difference of squares pattern:

$(3x^6 - 0.3y^2) \cdot (3x^6 + 0.3y^2) = (3x^6)^2 - (0.3y^2)^2$

Simplifying further:

$9x^{12} - 0.09y^4$
