Answer: 144
Step-by-step explanation: The problem shown here can be read as "10 to the 2nd," oe "12 to the 2nd power."
The 12 is called the base and the 2 that is raised up is called the exponent.
The exponent of 2 tells us that we multiply our base 2 times.
So we have 12 · 12 which is 144.
The numbers that we multiply together are called factors so in this problem, we have 2 factors of 12.
The plane speed in still air is the average of the two speeds: 430 miles/hour.
The wind speed is half the difference of the two speeds: 20 miles/hour.
