Can someone please solve this

Answer 1

• (⁴√2+⁴√8)²
• (⁴√2)²+(⁴√8)²+2(⁴√8×⁴√2)
• ⁴√2²+⁴√8²+2(⁴√16)
• ⁴√4+⁴√64+2(2)
• √2+4+2√2
• 4+3√2

Answer 2

• 
  `4+3√(2)`

Explanation:

• 
  `(\sqrt[4]{2}+\sqrt[4]{8})^2=`
• 
  `(\sqrt[4]{2})^2+ 2\sqrt[4]{2*8} +(\sqrt[4]{8})^2=`
• 
  `\sqrt[4]{4}+ 2\sqrt[4]{16} +\sqrt[4]{64}=`
• 
  `\sqrt[4]{4}+ 2*2 +2\sqrt[4]{4}=`
• 
  `√(2)+4+2√(2) =`
• 
  `4+3√(2)`
