ok

OpenStudy (baby_bear69):

Oh im sorry I saw my mistake its not 5 ^_^

OpenStudy (anonymous):

ya, didn't look right

OpenStudy (baby_bear69):

Step 1: Break the numbers to it's premises: \[28= 2^2 * 7\]

OpenStudy (baby_bear69):

Step 2: apply the exponent rule: \[\sqrt[n]{a * b} = \sqrt[n]{a} \sqrt[n]{b}\]

OpenStudy (baby_bear69):

Step 3: Take the root: \[\sqrt[n]{a^n}\]

OpenStudy (baby_bear69):

Which gets you \[2 * \sqrt{7}\]

OpenStudy (baby_bear69):
