To divide variables you subtract the exponents
y^(4/5 - 1/5) z^(2/3 - 1)
y^3/5 z ^(-1/3)
= y^3/5 over z^(1/3) to make the exponent positive

[y^(4/5)z&(2/3)] / y^(1/5)

when dividing you subtract exponents with the same bases...
4/5 - 1/5 = 3/5
2/3 - 1 = -1/3

y^(3/5) / z^(1/3) will be your answer...
