Example of Reciprocal of Square of 1 Less than Number Base
Expressed in base $6$, the reciprocal of $5^2$ has the expansion:
- $\dfrac 1 {5^2} = \sqbrk {0 \cdotp \dot 0123 \dot 5}_6$
Proof
From Square of $1$ Less than Number Base: $5$ we have:
- $5^2 = 41_6$
Performing the calculation using long division:
0.0123501... ---------------- 41)1.0000000000 41 -- 150 122 --- 240 203 --- 330 325 --- 100 41 -- ...
