OpenStudy (anonymous):

input 85 on the calculator and push the button that either looks like a check mark or says sqrt

OpenStudy (anonymous):

The button below the log function button.

OpenStudy (anonymous):

ok now what?

OpenStudy (anonymous):

what did it give you?

OpenStudy (anonymous):

85/ Whats the other number

OpenStudy (anonymous):

\[\sqrt{85}=9.2\] what 2 numbers is that between?

2

OpenStudy (anonymous):

no

OpenStudy (anonymous):

OpenStudy (anonymous):

More help please?

OpenStudy (anonymous):

ok :D

OpenStudy (anonymous):

OpenStudy (anonymous):

help

OpenStudy (anonymous):

ok for this we will have to do \[a^{2}+b^{2}=c ^{2}\]

OpenStudy (anonymous):

so the equation would be \[5^{2}+5^{2}=c^{2}\]

OpenStudy (anonymous):

so waht is \[5^{2}\]

OpenStudy (anonymous):

5 x 5 = 25

OpenStudy (anonymous):

Or is it edition?

OpenStudy (anonymous):

ok and 25+25 is 50 right?

OpenStudy (anonymous):

Yes

OpenStudy (anonymous):

then we find the square root of 50 which is?

OpenStudy (anonymous):

ugh

OpenStudy (anonymous):

7.07 ?

OpenStudy (anonymous):

Yep you got it!

OpenStudy (anonymous):

Thats not a choice

OpenStudy (anonymous):

:/ what are the choices then?

OpenStudy (anonymous):

OpenStudy (anonymous):

ok then its \[5 \sqrt{2}\]

OpenStudy (anonymous):

OpenStudy (anonymous):

only one of those can be simplified to a whole number. any of those that end in a decimal in a calculator are not rational

OpenStudy (anonymous):
