Step-by-step explanation:

You see how the line t is horizontal. That's 180 degree angle. So when broken out with angles 3 and 4, it should still add to 180

What are some easy ways to find the value of<br> (2017^4−2016^4)/(2017^2+2016^2) without calculator

scoray [572]

Answer:

4033

Step-by-step explanation:

An easy way to solve this problem is to notice the numerator, 2017^4-2016^4 resembles the special product a^2 - b^2. In this case, 2017^4 is a^2 and 2016^4 is b^2. We can set up equations to solve for a and b:

a^2 = 2017^4

a = 2017^2

b^2 = 2016^4

b = 2016^2

Now, the special product a^2 - b^2 factors to (a + b)(a - b), so we can substitute that for the numerator:

We can notice that both the numerator and denominator contain 2017^2 + 2016^2, so we can divide by $\frac{2017^2+2016^2}{2017^2+2016^2}$ which is just one, and will simplify the fraction to just:
