5. deerhunter15

cant be c or d

6. deerhunter15

i think b

Ok, we are going to wait for yoloshroom for his answer

8. YoloShroom

It's A

so what should i do b or a ?

10. YoloShroom

529^1/2 = 23, (529^1/2)^2 is 23. $\sqrt{529}=\sqrt{23^2}$

11. YoloShroom

In square root of 23, the Square of 23 cancels out with The Square root, since Sqaure root is the opposite of (to the power of)^2

12. YoloShroom

and since 23*23 =529, we can simplify the rational and say sqrt529=23 so 23=23

yeah i did test and a is correct thanks

14. YoloShroom
