Answer:

The value of given expression is 2

Step-by-step explanation:

Given: Expression is $x^0+y^0$

To find : Value of expression when x = 3 and y = 2

Consider,

$x^0+y^0$

To find value we put value of x = 3 and y = 2

$\implies 3^0+2^0$

Now we know that value of expression whose power 0 is 1 irrespective of value of base .i.e, $a^0=1$ ∀ a ∈ any no.

⇒ $3^0=1\:and\:2^0=1$

$\implies 3^0+2^0$ = 1 + 1

⇒ 2

Therefore, The value of given expression is 2

Good evening

x^0+y^0 for x=3 and y=2

First thing we need to do is to replace their value

3^0+2^0

Remember: Any number that raised to the zero power equal 1

so now we have

3^0=1 and y^2=1

1+1

= 2

Your attachment says: (-1/2) · (4x) · (-2) · (7y) · (-1)

Let's put together the
1st, 3rd, and 5th factors: (-1/2) · (-2) · (-1) = -1

So now we have    (-1) · (4x) · (7y)

Well       (4x) · (7y) = (4 · 7) · (x · y) = 28 · x · y

So all together we have    (-1) · (28 · x · y) = -28xy

$\left(-(1)/(2)\right)(4x)(-2)(7y)(-1)\n\n=\left(-(1)/(2)\right)(-2)(4)(7)(-1)(x)(y)\n\n=(1)(4)(7)(-1)(xy)\n\n=(28)(-1)(xy)\n\n=(-28)(xy)\n\n=\boxed{-28xy}\to\boxed{\boxed{A}}$
