Hey there! :D

[tex] \sqrt{x^2}+yz[/tex] (the square root sign should reach over the additional numbers)

Plug in the values. 

[tex] \sqrt{-2^2} + 8(1/2)[/tex]

Simplify. 

[tex] \sqrt{4+4} [/tex]

[tex] \sqrt{8} [/tex]

In simplest radical form, √8= 2√2

Or, as a decimal, 2.8 (rounded)

I hope this helps!
