The first one I think is D its been a while since I worked with powers
Break the fraction into seperate fractions that the numerator and chage the power to a negative then it will bring the numerator out chage powers common denom and add powers together

thx

Give you the 1st 2 steps for each:

1st one: m^(3/4) / m^(2/5) + m^(2/3) / m^(2/5)
= m^(3/4 - 2/5) + m^(2/3 - 2/5)


2nd one: z / [64z^(3/4) / z^(1/2)]^(1/3)
= z / 4[z^(3/4 - 1/2)]^(1/3)
