Evalute 2√72 divided by √8+ √2. I need help asap!!!<br><br><br> :( I will mark brainliest pls!!
Ghella [55]

Answer:

It's 4

Step-by-step explanation:

* / = square root

You simply 2/72 which is 12/2, then simplify /8 which is 2/2.

You combine 2/2 and /2 which is 3/2.

The equation should be 12/2 over 3/2 so you simplify it which will give you 4.

(By simplifying 12/2 over 3/2, you cross out /2 and convert 12 over 3 into a whole number)
