Think of how many times 2 needs to be multiplied in lodge to get eight.
2 x 2 = 4
four 10 2 = viii
Therefore, since iii '2'due south were used, x = iii

Think of how many times ii needs to exist multiplied in club to get 8.
2 10 2 = 4
iv 10 2 = 8
Therefore, since iii 'two's were used, 10 = 3

- $$ii^x=8\quad|\quad \ln{}$$
- $$\ln{(ii^x)}=\ln(eight)$$
- $$x*\ln{2}=\ln{eight}$$
- $$x=\frac{\ln{8}}{\ln{2}}=\frac{\ln{(two*two*ii)}}{\ln{ii}}=\frac{\ln{two}+\ln{ii}+\ln{2}}{\ln{2}}=\frac{\ln{2}}{\ln{ii}}+\frac{\ln{2}}{\ln{ii}}+\frac{\ln{2}}{\ln{ii}}=1+one+1=iii$$
- $$\boxed{x=3}$$

We can also equate bases to solve this.
two10 = eight
2x = 23
So, x = 3.
