#### Explanation:

There is no way to simplify this, other than writing this as

#y=log^3(78.5)=log(78.5)xxlog(78.5)xxlog(78.5)#

Note that this is **different** than the other logarithm rules:

#log(a^b)=bxxlog(a)#

#log(a)+log(b)=log(ab)#

**However,** the only way to find this is the use a calculator:

#y=log(78.5)xxlog(78.5)xxlog(78.5)=color(blue)(6.80358827392#
