Prove the divisibility of the following numbers: 45^10·5^40 by 25^20
beks73 [17]

For this case we have the following expressions:

45^{10} * 5^ {40} and 25^{20}

Let:

45^{10} * 5^ {40} (Integer m)

25^{20} (Integer n)

By definition, an integer m is divisible by an integer n if the remainder of the division is 0. That is, there is an integer p such that: m = n * p

Rewriting the expression we have:

25^{20} = 5^{2 * (20)} = 5^{ 40}

So:

\frac {45^{10} * 5^{ 40}} {5^{40}} =

We cancel similar terms:

45^{10}

We check:

45^{10} * 5^{ 40} = 5^{ 40} * 45^{ 10}

Answer:

If they are divisible
