I like value of x

Step-by-step explanation:

if if this is good please like

Answer 2

$\sf{\red{\boxed{\bold{Solution}}}}$

⠀⠀⠀⠀

$: \implies\: \sf{\bold{ \dfrac{1}{2} {x}^{4} {y}^{4} \times \dfrac{1}{3} {x}^{5} {y}^{3} \times \dfrac{2}{3} {x}^{3} {y}^{2}}}$

⠀⠀⠀⠀

• $\sf{\bold{ a^m\times a^n = a^{m+n}}}$

⠀⠀⠀⠀

$: \implies\: \sf{\bold{ \dfrac{1}{2}\times\dfrac{1}{3}\times\dfrac{2}{3}\times x^{4 + 5 + 3}\times y^{4 + 3 + 2}}}$

⠀⠀⠀⠀

$: \implies\: \sf{\bold{ \dfrac{1}{2}\times\dfrac{1}{3}\times\dfrac{2}{3}\times x^{12}\times y^{9}}}$

⠀⠀⠀⠀

$: \implies\: \sf{\bold{ \times\dfrac{1}{3}\times\dfrac{1}{3}\times x^{12}\times y^{9}}}$

⠀⠀⠀⠀

$: \implies\: \sf{\bold{ \dfrac{1}{9}\times x^{12}\times y^{9}}}$

⠀⠀⠀⠀

• putting value of x and y

⠀⠀⠀⠀

$: \implies\: \sf{\bold{ \dfrac{1}{9}\times -1^{12}\times 2^{9}}}$

⠀⠀⠀⠀

$: \implies\: \sf{\bold{ \dfrac{1}{9}\times 1 \times 512}}$

⠀⠀⠀⠀

$: \implies\: \sf{\bold{ \dfrac{512}{9}}}$
