You have the following expression
(mp/n)⁸
In order to simplify the previous expression, take into that the power of a quotient is the quotient of the numbers powered to the given exponents, just as follow:
(mp/n)⁸ = (mp)⁸/n⁸
next, consider that the power of a product is the product of the factors powered to the given exponent, then:
(mp)⁸ = m⁸p⁸
then, for the given expression, you obtain:
(mp/n)⁸ = (mp)⁸/n⁸ = m⁸p⁸/n⁸
Hence, the simplified expression is m⁸p⁸/n⁸
