Answer:

18 + √3

Step-by-step explanation:

The product of a surd and its conjugate gives a rational number. Hence;

(18 - √3) (18 + √3)

=324 + 18√3 - 18√3 - 3

=321

A rational number does not contain any surd, hence the answer.

If jummai is 12years old and Tunde is 8years old and they share 15bananas in the ratio of their ages how many will each have sho
bixtya [17]

Jummai and Tunde will each have 9 and 6 bananas respectively.

For the given ratio case we use the sharing ratio criterion to solve the problem.

Jummai is 12 years old.

Tunde is 8 years old.

Their ages are in ratio of;

                             A = 12 : 8

                             A =  3 : 2

The ratio's sum is 5.

15 bananas total are available for sharing.

Jummai will have x\\ bananas  x = (15 x 3/5) = 9

Tunde will have y bananas  y = (15 x 2/5) = 6

Jummai and Tunde will each have 9 and 6 bananas with them.
