Rewrite the root expressions as fractional exponents:

$\dfrac{\sqrt[3]{7}}{\sqrt[5]{7}} = \dfrac{7^{1/3}}{7^{1/5}}$

Recall that $\frac{a^m}{a^n} = a^{m-n}$ , so that

$\dfrac{7^{1/3}}{7^{1/5}} = 7^{1/3 - 1/5}$

Simplify the exponent:

$\dfrac13 - \dfrac15 = \dfrac5{15} - \dfrac3{15} = \dfrac{5-3}{15} = \dfrac2{15}$

Then you end up with

$\dfrac{\sqrt[3]{7}}{\sqrt[5]{7}} = 7^{2/15}$

There are only 3 patterns that exceed the sum of 10 which are: 5-6,6-5,6-6.
Which gives us 33 patterns. Which makes 33 sums not greater than 10.

Answer:

$z = \frac{5}{8} \\$

Step-by-step explanation:

$9z + (7z-4)=6 \\ 9z + 7z - 4 = 6 \\ 16z = 6 + 4 \\ 16z = 10 \\ z = \frac{10}{16} \\ \\ z = \frac{5}{8}$
