Answer:
1st, 2nd, and last.
Step-by-step explanation:
For the first two common rules can be applied such as
=
and that
and for the last one this is just simplifying the radical and if you factor it you realize that,
meaning that you can take the radical off of 5/8 and end up with that final answer
Its D because vertical angles are right across from each other!
Answer:
Step-by-step explanation:
So in this example we'll be using the difference of squares which essentially states that:
or another way to think of it would be:
. So in this example you'll notice both terms are perfect squares. in fact x^n is a perfect square as long as n is even. This is because if it's even it can be split into two groups evenly for example, in this case we have x^8. so the square root is x^4 because you can split this up into (x * x * x * x) * (x * x * x * x) = x^8. Two groups with equal value multiplying to get x^8, that's what the square root is. So using these we can rewrite the equation as:

Now in this case you'll notice the degree is still even (it's 4) and the 4 is also a perfect square, and it's a difference of squares in one of the factors, so it can further be rewritten:

So completely factored form is: 
I'm assuming that's considered completely factored but you can technically factor it further. While the identity difference of squares technically only applies to difference of squares, it can also be used on the sum of squares, but you need to use imaginary numbers. Because
. and in this case a=x^2 and b=-4. So rewriting it as the difference of squares becomes:
just something that might be useful in some cases.
Your answer would be ten times the ingredients it would take to make ONE pancake.
