When you raise an exponent to a power, you multiply the exponents. 8*3/4=6 x would be raised to 6.
For the first one, it's (a^8b^6). For the second one, it's 81m^8n^20.
Step-by-step explanation:
Draw lines from one vertex to the other vertices, splitting the polygon into triangles. If the polygon has n sides, there will be n−2 triangles. Each triangle's angles add up to 180°. So the sum of all the interior angles is:
S = (n−2) 180°
