![\huge \pink {\tt {{128}^{ \frac{3}{7} } = \sqrt[7]{ {128}^{3} } = {2}^{3} }}](https://tex.z-dn.net/?f=%20%5Chuge%20%5Cpink%20%7B%5Ctt%20%7B%7B128%7D%5E%7B%20%5Cfrac%7B3%7D%7B7%7D%20%7D%20%20%3D%20%20%5Csqrt%5B7%5D%7B%20%7B128%7D%5E%7B3%7D%20%7D%20%20%3D%20%20%7B2%7D%5E%7B3%7D%20%20%7D%7D%20)
<h2>Answer:</h2>
x > 7 x < 10
7 o---------------------o 10
This is not an empty set. x contains all of the values between 7 and 10.
138 x ? = 75
? = 75/138 = 0.544(3sf)
so about 54.35% (2dp) decrease
