a)(√32+√2)/√2 =(4√2+√2)/√2 =5√2/√2 =5
b)(√27-√12)/√3 =(3√3-2√3)/√3 =√3/√3=1
c)√2(√8+√50)=√16+√100 =4+10=14
d)(2√50+√72) /2√2 =(10√2+6√2)/2√2 =16√2 /2√2 =8
(√32+ √2)/√2= (√(16*2)+ √2)/√2=(4√2+√2)/√2=(5√2)/√2=5
(√27-√12)/√3= (√(9*3)- √(4*3))/√3=(3√3-2√3)/√3=√3/√3=1
√2(√8+√50)=√16+ √100=4+10=14
(2√50+√72)/(2√2)= (√(4*50)+ √72)/√(4*2)=(√200+√72)/√8=√272/√8= √(272/8=34)
