A book shows an enlarged photo of a carpenter bee. A carpenter bee is about 6×10^-3 m long. The photo is 13.5 cm long. About how many times as long as a carpenter bee is the photo?

Answers

A ratio compares values. A ratio says how much of one thing there is compared to another thing. We do as follows:

length of photo/ length of a carpenter bee = ratio of the two
13.5 / 6x10^-3 = 2250

Therefore, the photo is 2250 longer than the carpenter bee.

Answer:

1/5 · 1/5 · 1/5 · 1/5

Step-by-step explanation:

One way of interpreting exponents is as repeated multiplication. When you see (1/5)⁴, you can read that as "4 copies of 1/5, multiplied together." That expansion looks like (1/5)⁴ = 1/5 · 1/5 · 1/5 · 1/5
