Question 236331
n = 80% of p means that:


n = .8*p


take the square root of both sides of this equation and you get:


sqrt(n) = sqrt(.8*p) = sqrt(.8) * sqrt(p)


sqrt(.8) = .894427191 * 100% = 89.4427191%


your answer is:


sqrt(n) = 89.4427191% of sqrt(p)


to confirm, let n = 100


this makes p = 100/.8 = 125


equation of


n = .8*p becomes


100 = .8*125


take sqrt of both sides to get:


sqrt(100) = sqrt(.8*125) = sqrt(.8) * sqrt(125)


this becomes:


10 = .894427191 * 11.18033989


this becomes:


10 = 10


Answer is confirmed.
