Simplified form of square root of 72

the simplified form

6√2

Step-by-step explanation: The easiest way to do this problem is to factor 72 as 2 · 36 then recognize 36 as a perfect square, 6 · 6.

There is no need to factor further because the 6's pair up.

So a 6 comes out of the radical leaving a 2 inside.

Since the 2 doesn't pair up, it becomes the radicand.

When simplifying radicals using the factor tree,

always be on the lookout for perfect squares.

hello, sorry being so rude after all that fighting i found it kind of funny, so as me saying sorry here is an answer!

since the table showed her that   2km = 2000m.

to determine, how many km in 2000m, she would divide by 1000.

= 2000 / 1000 = 2 km.

similarly, for 8000m = 8000 / 1000 = 8 km

cheers to savings
