The student that solved it correctly is Harry.
However, the answer needs to be 32 pixels because the height of the icon must be a non-negative value (since pixels cannot be negative).
I think icon, I think icon.
Ally is creating a web page using square icons to link to different pages. Each square icon contains 1024 pixels (dots), arranged in rows. Each side of the square contains the same number of pixels.
FLAT WEB ICONS
Ally needs to know how many pixels (p) tall her icons are. She writes p ^ 2 = 1024 to find the value of p.
Four students attempt to do the calculations to find the number of pixels tall her icons are. Their work is shown in the table below.
Harry
p ^ 2 = 1024
sqrt(p ^ 2) = sqrt(1024)
p = 32
Sherlock
p ^ 2 = 1024
p = 1024 ^ 2
p = 1048576
Frodo
p ^ 2 = 1024
sqrt(p ^ 2) = plus/minus sqrt(1024) sqrt(p ^ 2) = sqrt(1024) * or * sqrt(p ^ 2) = - sqrt(1024) p = 32 or p = - 32
Elizabeth
p ^ 2 = 1024
(p ^ 2)/2 = 1024/2
p = 512
