There are several mathematical calculation problems, to complete the process. (1) √ 6 ×√ 3 / √ 2 (2) √ 12 - √ 3 / √ 3-1 (3)(√2-√3)²+(2√2+1)(2√2-1) (4)5√2+√8-7√18

There are several mathematical calculation problems, to complete the process. (1) √ 6 ×√ 3 / √ 2 (2) √ 12 - √ 3 / √ 3-1 (3)(√2-√3)²+(2√2+1)(2√2-1) (4)5√2+√8-7√18

(1)√6×√3/√2=√18/√2=3√2/√2=3 (2) √12-√3/√3-1 =2√3-(3√3/3)-1=6√3/3-(3√3/3)-1=√3-1 (3)(√2-√3)²+(2√2+1)(2√2-1) =(2+3-2√6)+(8-1)=5-2√6+7=12-2√6(4)5√2+√8-7√18=5√2+2...
