Answer 2

Answer:

$1 \div( 7 - \sqrt[4]{3} ) = \\ 1 \div 7 - (4 \sqrt{3 }) \times (7 + (4 \sqrt{3})) \div 7 + (4 \sqrt[]{3} ) \\ = (7 - 4 \sqrt{3 } ) \div 7 ^{2} - 16 \times 3 \\ = (7 - 4 \sqrt{3} ) \div 49 - 48 \\ = (7 - 4 \sqrt{3) }$

$1 \div( 7 - \sqrt[4]{3} ) = \\ 1 \div 7 - (4 \sqrt{3 }) \times (7 + (4 \sqrt{3})) \div 7 + (4 \sqrt[]{3} ) \\ = (7 - 4 \sqrt{3 } ) \div 7 ^{2} - 16 \times 3 \\ = (7 - 4 \sqrt{3} ) \div 49 - 48 \\ = (7 - 4 \sqrt{3) }$this is the answer....
