n is an arbitrary real number. By only using multiplication, you are asked to find n23 with the least amount of multiplication operation.
Note: You can only use n or the results you can with multiplications as examplified below.
For example if this question is asked for n4, the answer would be 2:
1.
n×n=n2
2.
n2×n2=n4
Answer
1.
n×n=n2
2.
n×n2=n3
3.
n3×n2=n5
4.
n5×n5=n10
5.
n10×n10=n20
6.
n20×n3=n23
