medal!!! am i correct? read below for problem

OpenStudy (lexber):

\[\sqrt{3}\sqrt{6}\]

OpenStudy (lexber):

is ^ equal to 6 1/3

OpenStudy (welshfella):

sqrt3 * sqrt 6 = sqrt18 = sqrt9 * sqrt2 what is the square root of 9 ?

OpenStudy (lexber):

3

OpenStudy (welshfella):

right so sqrt9 * sqrt2 = 3 sqrt 2

OpenStudy (welshfella):

thats your final answer

OpenStudy (lexber):

so 6 1/3 is equal to \[\sqrt{3\sqrt{6}}\] ?

OpenStudy (lexber):

@welshfella

OpenStudy (welshfella):

?? i dont follow you I took it that the problem was sqrt3 times square root of 6

OpenStudy (lexber):

the question is which of the following is equal to \[\sqrt{3\sqrt{6}}\] ? and here are the answer choices A; 6 1/6 B; 6 1/3 C; 6 2/3 D; 6 3/2

OpenStudy (welshfella):

oh ok

OpenStudy (lexber):

@welshfella i think that the answer is B but i dont know if i am correct

OpenStudy (welshfella):

well sqrt6 = 2.449 3 * 2.449 = 7.347 and sqrt 7.347 = 2.711 so none of them is correct

OpenStudy (lexber):

well which one seems closest to the right answer? @welshfella

OpenStudy (welshfella):

none of them are close

OpenStudy (lexber):

i dont know what to put for it ):

OpenStudy (welshfella):

there must be something wrong with the question

OpenStudy (lexber):

im going to take a screen shot of the question in case im typing it wrong @welshfella

OpenStudy (welshfella):

ok

OpenStudy (lexber):

@welshfella

OpenStudy (welshfella):

Ah !! right convert the radicals to fractional indices so

OpenStudy (lexber):

so is my answer correct?
