Immortal numbers

Immortality of Split Complex

Approximation for various powers at base 10, using immortal split complex with 1-5 digits and only positive parts;
2 is subtracted from the amount of integers in order to exclude the super immortal numbers 0 and 1:

$|\mathbb{M}^{power}_{10}|^{\mathbb{D}^{+}}\approx\tfrac{true\ split\ complex\ % numbers+integers-2}{{5}^{2}}$

$|\mathbb{M}^{2}_{10}|^{\mathbb{D}^{+}}\approx\tfrac{56+10-2}{{5}^{2}}=2.56$

$|\mathbb{M}^{3}_{10}|^{\mathbb{D}^{+}}\approx\tfrac{1519+48-2}{{5}^{2}}=62.6$

$|\mathbb{M}^{4}_{10}|^{\mathbb{D}^{+}}\approx\tfrac{91+10-2}{{5}^{2}}=3.96$

$|\mathbb{M}^{5}_{10}|^{\mathbb{D}^{+}}\approx\tfrac{11641+121-2}{{5}^{2}}=470.4$

$|\mathbb{M}^{6}_{10}|^{\mathbb{D}^{+}}\approx\tfrac{887+42-2}{{5}^{2}}=37.08$

$|\mathbb{M}^{7}_{10}|^{\mathbb{D}^{+}}\approx\tfrac{1419+48-2}{{5}^{2}}=58.6$

$|\mathbb{M}^{8}_{10}|^{\mathbb{D}^{+}}\approx\tfrac{93+10-2}{{5}^{2}}=4.04$

$|\mathbb{M}^{9}_{10}|^{\mathbb{D}^{+}}\approx\tfrac{23934+158-2}{{5}^{2}}=963.6$

$|\mathbb{M}^{10}_{10}|^{\mathbb{D}^{+}}\approx\tfrac{99+10-2}{{5}^{2}}=4.28$
