Final Answer :
C
Explanation :
We can simplify the expression by distributing the square root of 35: 35(7+10)=35⋅7+35⋅10=245+350\sqrt { 35 } ( \sqrt { 7 } + \sqrt { 10 } ) = \sqrt{35 \cdot 7} + \sqrt{35 \cdot 10} = \sqrt{245} + \sqrt{350}35(7+10)=35⋅7+35⋅10=245+350 We can simplify further by finding the prime factorization of 245 and 350. Note that both have a factor of 7, so we can factor out 7\sqrt{7}7 from both terms: 245+350=7⋅35+7⋅50=75+514\sqrt{245} + \sqrt{350} = \sqrt{7\cdot 35} + \sqrt{7\cdot 50} = 7\sqrt{5} + 5\sqrt{14}245+350=7⋅35+7⋅50=75+514 Therefore, the answer is choice C.
