Final answer:
When magnifying an object by ten to the power of three, you multiple the base, which is ten, by itself three times, resulting in a magnification of 1,000 times.
Step-by-step explanation:
If you magnify the image of a cluster fly by ten to the power of three times, you are essentially magnifying it by ten times, and then again by ten times, and a third time by ten times. When dealing with magnification or any process that is repeated multiple times, you use exponential growth. Hence, you multiply 10 (the base) by itself three times (the exponent), resulting in 10 x 10 x 10, which equals 1,000 times.
However, if we reconsider the phrasing and assume that it’s asking for the compounded result (10 to the power of 3), the magnification would indeed be 10^3, which equals 1,000 times.
