Answer:

$p = \pm (√(r(st - 1)))/(st - 1)$

or

p = (√(r(st - 1)))/(st - 1)

Explanation:

t = (p^2 + r)/(p^2s)

p^2st = p^2 + r

p^2st - p^2 = r

p^2(st - 1) = r

p^2 = (r)/(st - 1)

$p = \pm \sqrt{(r)/(st - 1)}$

Your picture cuts out the assumption. If the assumption is that all variables are non-negative, then the answer is

$p = \sqrt{(r)/(st - 1)}$

p = (√(r))/(√(st - 1))}

p = (√(r))/(√(st - 1))} * (√(st - 1))/(√(st - 1))

p = (√(r) √(st - 1))/(√(st - 1)√(st - 1))

p = (√(r(st - 1)))/(st - 1)
