diketahui nilai √2 = 1,41 √3 = 1,73 dan √5 = 2,24 tentukan nilai akar bilangan berikut dibulatkan sampai 1 desimal! a) √12 b) √18 c) √80 d) √98 e) √75 f) √405 g

a) √12 = √4 x 3 = 2√3 = 2 x 1,73 = 3,5

b) √18 = √9 x 2 = 3√2 = 3 x 1,41 = 4,2

c) √80 = √16 x 5 = 4√5 = 4 x 2,24 = 8,9

d) √98 = √49 x 2 = 7√2 = 7 x 1,41 = 9,9

e) √75 = √25 x 3 = 5√3 = 5 x 1,73 = 8,7

f) √405 = √81 x 5 = 9√5 = 9 x 2,24 = 20,2

g) √147 = √49 x 3 = 7√3 = 7 x 1,73 = 12,1

h) √200 = √100 x 2 = 10√2 = 10 x 1,41 = 14,1
