11^500 plus 25^500 + 36^500
$$y=11^{500} \\\\
logy=log11^{500}\\\\
logy=500log11\\\\
logy=520.6963426\\\\
y=10^{520.6963426}\\\\
y=10^{0.6963426}*10^{520}\\\\
y=4.969842206\times 10^{520}\\\\
11^{500}=4.969842206\times 10^{520}$$
Now you can copy the technique and do the others then add them together :)
