73.24
Step-by-step explanation:
78 - 6.5%(4.76) = 73.24
The answer will be 0 because anything to the power 0 is 0
We can use Pythagorean theorem for right angle triangle to solve this problem.
The diagonal line would be hypothenuze. Horizontal and vertical distance would be other two sides of a triangle.
We will use the following formulas:

Where opposite side is vertical distance and adjacent side is horizontal distance.
Solving for these two sides we have:

We insert numbers and we get solution:
Percent is simply /100, so the fraction would be 450/100. Divide both top and bottom and you will get 9/2, or 4 1/2
20,484, 163 = 2x10,000,000 + 4x100,000 + 8x10,000 + 4x1,000 +1x100 +6x10 +3x1
Hope this helps :P
