15 radical 5 is 15 radical 5 u cant simplify anymore
OpenStudy (anonymous):
No I need it to EQUAL radical 225
OpenStudy (anonymous):
oh 15 radical 5 has to equal 225?
OpenStudy (anonymous):
225 equals 15 times 15
OpenStudy (anonymous):
so leave 15 alone and you ahve to do something with radical 5 to be 15

\[\sqrt{5}\times something has \to equal 15\]
OpenStudy (anonymous):

OpenStudy (anonymous):
as in example
OpenStudy (anonymous):

which is radical 5 times radical 45
OpenStudy (anonymous):
so the answer is radical 45
OpenStudy (mertsj):
\[15\sqrt{5}=\sqrt{15^2(5)}=\sqrt{1125}\]
OpenStudy (anonymous):
\[15\sqrt{5}\times \sqrt{45}=225\]
OpenStudy (anonymous):
My choices to pick from are
15
25
15 radical 5
10 radical 2
