#(1/4)^5 * 4^13#

Follow the rule from above and apply it to the first term.

#(1*1*1*1*1)/(4*4*4*4*4) * 4^13#

#1/1024 * 4^13#

Now evaluate the second term.

#1/1024 * (4*4*4*4*4*4*4*4*4*4*4*4*4)#

#1/1024 * 67108864#

Rewrite as fractions and multiply.

#1/1024 * 67108864/1#

#(1times67108864)/(1024times1)#

#67108864/1024#

Simplify the fraction.
