C. 9 square roots of 2
To answer this question, it's super important that you understand the ratio of sides for special triangles. This triangle in particular, a 45-45-90 triangle, has a ratio between the legs and hypotenuse of 1:1:
Since we are given the value of the hypotenuse, we know that the value of the two sides multiplied by
will be 18. Knowing this, we can write out an equation:
u*
= 18
u = 
<u>Multiply both sides by </u>
<u> in order to get rid of the root in the denominator:</u>
u = 
u = 
u = 9
If you'd like me to explain how I got to the answer any further, just ask!

To simplify 10^6/10^-3 you first need to get rid of the negative exponents so you bring up 10^-3 so it becomes:
10^6x10^3 then all that you have to do is add the exponents since the bases for both are the same.
So the final answer is:
10^9
Or in other words:
10 to the power of 9
The number is 4. 15-6=8 divide that by 2 and you are left with 4
