**Just pretend there's a square root sign where the question marks are** Is there a way to find the square root of a number containing a radical? For example: ?10?10 Is there a way to find the square root of that? I'm down to finding the square root of the both sides and I have... ?x = ?10?10 Thanks. ---------------------------------------- [Edit 1 times, last edit by EternalSummer247 at Jan 18, 2008 9:55:10 AM] |

You can write the square root of the square root of 10 as follows: ((10)^(1/2))^(1/2)=10^(1/4) That is, it can be rewritten as the fourth root of 10. Now that is a symbolic number, like the square root of 2, and you can get an approximation to it using decimals, but the symbolic expression is exact and there is no need to "simplify" it further. ---------------------------------------- Principal Skinner |

***Question marks are square root signs...except for the last one :) I probably should have posted the original problem first... ?3x-2x = ?1000 so would the most simplified form just be ?10?10? Thanks! |

(1000)^(1/2)=10*10^(1/2) ---------------------------------------- Principal Skinner |
