x66 = 122.436

D.

x6 = 124.4566

Correct Answer: x6 = 424.56

Explanation

(159.75)10 = (y)6 15910 = 4236 Then Convert 0.75 to base 6 0.75 x 6 =4.5 i.e 4.5 - 3.00 = 1.5 0.5 x 6 = 3.00 423 + 1.5 =424.5 159.75 = (424.5)6 (159)10 = (424.5)6

(159.75)10 = (y)6 15910 = 4236 Then Convert 0.75 to base 6 0.75 x 6 =4.5 i.e 4.5 - 3.00 = 1.5 0.5 x 6 = 3.00 423 + 1.5 =424.5 159.75 = (424.5)6 (159)10 = (424.5)6
