Step-by-step explanation:
This leads to another rule for exponents—the Power Rule for Exponents. To simplify a power of a power, you multiply the exponents, keeping the base the same. For example, (23)5 = 215. For any positive number x and integers a and b: (xa)b= xa· b.
Answer:
2^1
First combine like terms so
2x+6=3x-8
3x - 2x =1X
-6 - -8= -14
1X ÷ -14
then just divide
Mary loves to paper bows, for every paper bow she cuts out she will have enough scraps to make 1/3 of another. Let X equal the number of bows Mary has made, and Y equal the number of bows Mary can make with the scraps.

Answer:
The astronaut must be at 1600 km from the earth to weight 64lb
Step-by-step explanation:
As the weight of an object varies inversely as the square of the distance from the center of the earth, that means that:
weight = k / distance² <em>(1)</em>
Where k is proportionality constant
Replacing:
100 lb = k/(6400km)²
100lb × 6400km² = k = 4,096x10⁹ lbkm²
Now, using (1):
64 lb = 4,096x10⁹ lbkm² / x²
x² = 4,096x10⁹ lbkm² / 64lb
x² = 6,4x10⁷ km²
x = √6,4x10⁷ km²
x = 8000 km
Distance from the center of the earth is 8000 km. Distance from the earth (At sea level):
8000km - 6400km =<em> 1600km</em>
