Question

Please help! i can’t write the equation on here so look at the picture.

Answer 1

• √100 / {-5-1}^² +(-20)
• 10/(-6)^² -20
• 10/36-20
• 10/16
• 5/8

Answer 2

So if x= 1 , y= -20 , z = -5 , we just have to replace those values on the equation

`(√(yz))/((z-x)^(2) + y ) =`
`(√((-20) * (-5)))/((-5-1)^(2) + (-20) ) =`
`(√(100))/((-6)^(2) -20 )`
`= (10)/(16) =(5)/(8)`
