Answer 1

7√3-5√2/√48+√18

=7√3-5√2(√48-√18)/(√48+√18)(√48-√18)

=7√3-5√2(√48-√18)/(√48)^2-(√18)^2

=7√3-5√2(√48-√18)/48-18

=7√3-5√2(√48-√18)/30

=7√3-5√2/(4√3-3√2)/30

=7√3(4√3-3√2)-5√2(4√3-3√2)/30

=84-21√6-20√6+30/30

=84-41√6 (If you liked my answer then please mark me as brainliest and I will definitely follow you back.)
