Answer 2

Answer:

25

Step-by-step explanation:

Given : $4 \sqrt{81} -8\sqrt[3]{343} +15\sqrt[5]{32} +\sqrt{ 225}$

To Find : Value

Solution:

$4 \sqrt{81} -8\sqrt[3]{343} +15\sqrt[5]{32} +\sqrt{ 225}$

$\sqrt{81}=9$

$\sqrt[3]{343} =7$

$\sqrt[5]{32} =2$

$\sqrt{ 225} =15$

Substitute the values

$4(9) -8(7)+15(2) +(15)$

$25$

Hence $4 \sqrt{81} -8\sqrt[3]{343} +15\sqrt[5]{32} +\sqrt{ 225}=25$
