√ (7/100)=√7/√100
=√7/10
√( 3x/2) = √3x/ √2
=√3x/ √2 X √2/√2
= √2 √3x/√2 X √2
=√6x/2
√(20/5) - 1/√5
=√20/√5-1/√5
=(√20-1)/√5
=(2√5 - 1)/√5
a√8-3√2a^2
=2a √2 - 3a√2
=- a√2

√ 7/100 = 1/10 √ 7
√20/5 - 1/√5 = (√20-1)/√5

√(7/100)=√7/√100=√7/10
√3x√2=√(3x2)=√6
√20/5 - 1/√5= √20/(√5x√5) - 1/√5 = 1/√5 x (√20/√5 - 1) =
1/√5 x (√(20/5) – 1) = 1/√5 x (√4 – 1) = 1/√5 x (2-1) =
1/√5 x (1) = 1/√5 = √5/5

sqrt(7)/100=.01*sqrt(7)
sqrt(3x)/2=sqrt(3/4)*x^0.5=sqrt(0.75)*x^0.5
sqrt(20)/5-1/sqrt(5)=2sqrt(5)/5-1/sqrt(5)=2/sqrt(5)-1/sqrt(5)
=1/sqrt(5)=sqrt(5)/5
asqrt(8)-3sqrt(2)*a=2asqrt(2)-3asqrt(2)=-asqrt(2)
