If you get confused by logarithms, here's an easier way to think about this problem: What power of 2 equals 128? Well, we know 2^3 = 8, then 2^4 must equal 16. Doubling every times, we get 2^5 = 32, 2^6 = 64 and 2^7 = 128. So, the value of log₂128 is 7.
Answer:
Step-by-step explanation:
You already know the area, so just reverse the steps. Example: 200ft divided by the length which is 16ft equals 12.5 feet
3 feet deep for 5 feet high
17 feet high
17×3 = 51
He has to dig a hole 51 feet deep.
