Answer:
I will answer in English.
We want to compare the numbers 5^87 and 25^36
First, let's write them in the same base.
remember the relations:
(a^x)^y = a^(x*y)
a^x/a^y = a^(x - y)
We know that 25 = 5^2
Then:
25^36 = (5^2)^36 = 5^(2*36)= 5^72
Now to compare them, we take the quotient:
(5^87/5^72) = 5^(87 - 72) = 5^15
Then we can conclude that:
5^87 is 5^15 times bigger than 25^36
