Answer:

p = ±16

Step-by-step explanation:

p^2 =256

There will be two solutions since p is to the second power.

Take the square root of each side

sqrt(p^2) = sqrt(256)

p = ±16

[tex]p^2=256\iff p=\pm\sqrt{256}\\\\\sqrt{a}=b\iff b^2=a\\\\p=-16\ or\ p=16[/tex]

[tex]\text{because}\ 16^2=256\ and\ (-16)^2=256[/tex]
