Question

两道数学题，计算的

1、√75 - 2√1/27 + √1/3
2、根号12+根号24除以根号3 -2√1/2
(第二题我怕乱了所以写成文字)
要有过程，越快越好，现在要

Answer 1

1
=5√3-（2/9）√3+（1/3）√3
=【5-（2/9）+（1/3）】√3
=（46/5）√3

2
=2√3-2√6÷√3-√2
=2√3-2√2-√2
=2√3-3√2

Answer 2

1、√75 - 2√1/27 + √1/3
=5√3-2/9√3+1/3√3
=(5又1/9)√3

2、根号12+根号24除以根号3 -2√1/2
=2√3+2√2-√2
=2√3+√2

Answer 3

1. √75 - 2√1/27 + √1/3 = 5√3 -(2/9)√3 + (1/3)√3
=[ 5- (2/9) + (1/3)] √3= (46/9)√3

2. √12 + √24 / √3 - 2√1/2 = 2√3 + 2√2 - √2 = 2√3 + √2)
