Prove that the product of any two consecutive natural numbers is even.

Vitek1552 [10]

Answer with Step-by-step explanation:

Let us assume the 2 consecutive natural numbers are 'n' and 'n+1'

Thus the product of the 2 numbers is given by

$Product=n(n+1)\\\\$

We know that the sum of 'n' consecutive natural numbers starting from 1 is

$S_n=\frac{n(n+1)}{2}\\\\\therefore n(n+1)=2\times S_n............(i)$

Thus from equation 'i' we can write

$Product=2\times S_n$

As we know that any number multiplied by 2 is even thus we conclude that the product of 2 consecutive numbers is even.

Mandy has six boxes of pencils each box contains 10 to the fifth power of pencils how many pencils does Mandy have

Nonamiya [84]

You have to do 10•10•10•10•10 (multiply 10, 5 times). Once you multiply 10 five times, you end up with an answer of 100,000 pencils in each box. Then since you have 6 boxes of pencils you have to multiply 100,000•6, which equals 600,000 pencils total.
