(1).(根号44)*[-(根号33)]

(2).根号[(3.5)^2+(8.4)^2]

答案+过程!~ 谢!!!!!!!!~~~~~~~~~~~~

(1)(根号44)*[-(根号33)]
=-2*根号11*根号3* 根号11
=-22*根号3

(2)根号[(3.5)^2+(8.4)^2]
=根号[0.5^*7^+1.2^*7^]
=根号[7^*(0.5^+1.2^)]
=根号[7^*1.3^]……（此步是根据5、12、13为一组勾股数5^+12^=13^）
=根号[7*1.3]^
=7*1.3
=9.1

How foolish you are!!!!!!!!!!!!!!!!
You must do it all by yourself!!!!!

(1)(根号44)*[-(根号33)]
