Answer:

-12y^10

Step-by-step explanation:

First let's rewrite the equation using the commutative property of multiplication
3 x (-4)y^8y^2

Multiply y^8 by y^2 by adding the exponents
y^8+y^2= y^10

3 x (-4)y^10

Now multiply 3 by -4
3 x -4= -12

Finally put them together
-12 + y^10= -12y^10

Answer:

[tex] - 12 {y}^{10} [/tex]

Step-by-step explanation:

We are to simplify:

[tex](3 {y}^{8} )( - 4 {y}^{2} )[/tex]

3 multiplies -4 to get -12, as shown below

[tex]3 \times - 4 = - 12[/tex]

Now, to multiply the exponents which are 8 and 2, we have to use the exponential rule of multiplication: [tex] {a}^{b} \times {a}^{c} = {a}^{b + c} [/tex]

Therefore:

[tex] {y}^{8} \times {y}^{2} = = > {y}^{8 + 2} = {y}^{10} [/tex]

Now, combine -12 and [tex] {y}^{10} [/tex] to get your final answer.

Final answer [tex] = - 12 {y}^{10} [/tex]

I hope this helps
