Steady-state creep data taken for a stainless steel at a

Steady-state creep data taken for a stainless steel at a stress level of 70MPa (10,000psi) are given

If it is known that the value of the stress exponent n for this alloy is 7.0, compute the steady-state creep rate at 1250 K and a stress level of 50MPa(7250psi).
