Answer:
D and E
Step-by-step explanation:
Using the rule of radicals
⇔ ![\sqrt[n]{a^{m} }](https://tex.z-dn.net/?f=%5Csqrt%5Bn%5D%7Ba%5E%7Bm%7D%20%7D)
Given
![3^{\frac{4}{7} }](https://tex.z-dn.net/?f=3%5E%7B%5Cfrac%7B4%7D%7B7%7D%20%7D)
= (
)^4 → D or
=
=
→ E

The old machine can print 100 copies per hour.
Step-by-step explanation:
Given,
Copies printed per hour by new machine = 205 copies
Let,
x represent the number of copies by old machine.
According to given statement;
Copies printed by new machine = five more than twice the number of copies per hour of the old copy machine.
![205=2x+5\\205-5=2x\\200=2x\\2x=200](https://tex.z-dn.net/?f=205%3D2x%2B5%5C%5C205-5%3D2x%5C%5C200%3D2x%5C%5C2x%3D200)
Dividing both sides by 2
![\frac{2x}{2}=\frac{200}{2}\\x=100](https://tex.z-dn.net/?f=%5Cfrac%7B2x%7D%7B2%7D%3D%5Cfrac%7B200%7D%7B2%7D%5C%5Cx%3D100)
The old machine can print 100 copies per hour.
