Answer 1

Answer:

256x^8 y^20

that's the answer I got when I simplified it

Answer 2

Answer:

$=256x^8y^{20}$

Step-by-step explanation:

We have the expression:

$(4x^2y^5)^4$

We can use the power of a product property:

$(ab)^x=a^xb^x$

This yields:

$=(4)^4\cdot(x^2)^4\cdot(y^5)^4$

We can evaluate 4 to the fourth:

$=256(x^2)^4\cdot(y^5)^4$

Now, we can use the power of a power property:

$(x^a)^b=x^{ab}$

So:

$=256(x^{2(4)})(y^{5(4)})$

Multiply:

$=256x^8y^{20}$

And we're done!
