Maths Question

[CHARNA]

What 2 numbers to you need to multiply to get to 10,000. without using a 0

[AlwaysConfused]

16 x 625 = 10,000

[CHARNA]

Thank you very much AlwaysConfused.

[AlwaysConfused]

Happy to help, Charna

[Old_Geezer]

Well... zero times anything is zero anyway :-)

I think CHARNA means without using the digit 0 in the 2 (whole?) numbers that you multiply OG.

[Prudie]

And of course -16 x - 625
:-)

Is this for school, Charna?
Prime factor decomposition (factor trees) is a good way to tackle this.
The number breaks down to
2⁵ x 5⁴

[factor-fiction]

Ha ha- typo

[factor-fiction]

Epic fail when trying to be clever with typing indices. Should say:
2⁴ x 5⁴

[factor-fiction]

We've assumed we are talking about whole numbers, but if you allow fractions or recurring decimals you can have answers such as:
3333⅓ x 3

[ToraToraTora]

if you allow fractions there is an infinite number of combinations
