Edos are for calculating approximate logarithms in mathematics. The right choice of an edo (such as 53edo or even 612edo for 5-limit numbers) would give accurate results.

Which number is the biggest? A. 81^56 B. 9^100 C. 27^72 D. 2^224

53log₂(81^56)≈18816

53log₂(9^100)≈16800

53log₂(27^72)≈18144

53log₂(2^224)=11872

**A.**

³√(2 7/9)÷³√(3/5) rounded to the nearest integer is A. 1 B. 2 C. 3 D. 4

53log₂(³√(25/9)÷³√(3/5))≈39

2^(39÷53)≈5÷3

round(5÷3)=2

**B.**

Which number is the smallest? A. 5√3 B. 4√7 C. 8√2 D. 3√11

41log₂(5√3)≈127.5

41log₂(4√7)≈139.5

41log₂(8√2)=143.5

41log₂(3√11)≈136
