Title: 6 8's
Post by Altamira_64 on Jan 10^th, 2012, 10:25am

Form the number 1000 by using 6 8's and only +, -, *, / sqrt and parentheses ().

The simplest I find is [hide] (888-88)/.8 [/hide].

Decimal .8 is not allowed because it assumes there is a leading zero (0.8) :(

sqrt( sqrt(8 ) + sqrt(8 ) )⁸ - 8 - 8 - 8

I don't see exponents among the allowed operations.

It depends if the constraint lists the operations you can use or the symbols you can use.
Same for the numbers. Do the 8's refer to digits or numbers?

The constraint refers to operations allowed. Exponents are allowed, provided they result as a combination of eights.
