Help adek saya ... mohon bantuannya yha...

Answer 1

A. 1/(5-√3) = (1/(5-√3)) x(5+√3)/(5+√3)=(5+√3)/(25-3)=(5+√3)/22
b.( 4-√2)/(4+√2)=(4-√2)/(4+√2)x((4-√2)/(4-√2))=((16-(2x4√2)+2)/(16-2)=(18-8√2)/14
c.2a/(3a+√5)=2a/(3a+√5)x(3a-√5)/(3a-√5)=(6(a^2)-2a√5)/(9a-5)
d.√3/(√5-√10)=√3/(√5-√10)x(√5+√10)/(√5+√10)=(√15+√30)/(5-10)=(√15+√30)/-5
e. xy/(√x+√y)=xy/(√x+√y)x(√x-√y)/(√x-√y)=(xy√x-xy√y)/x-y
f. (√24+√54-√150)/√96 =sama-sama dibagi√6
=(√4+√9-√25)/(√16)=(2+3-5)/4=0/4 = 0
