Answer:

a=8

Explanation:

First make the denominators whole numbers.

22
√(3)/3 + 6
√(27)/27

Now make the denominators the same. To change 3 to 27, multiply by 9.

198
√(3)/27 + 6
√(27)/27

simplify6
√(27) which is 6
√(9)
√(3) simplified to 6 x 3
√(3)=18
√(3)

(198
√(3)+18
√(3))/27

198 plus 18 is 216

216
√(3)/27

216 divided by 27 is 8

8
√(3)

8 is in the place of a in the equation a
√(3) so a = 8

Answer: To solve the expression 22 /√3 + 6 /√27, we need to rationalize the denominator of the second term. We can do this by multiplying both the numerator and denominator of the second term by √3. This gives us:

22 /√3 + 6 /√27

= 22 /√3 + 6 * √3 / (√3 * √3 * √3)

= 22 /√3 + 6 * √3 / 3√3

= 22 /√3 + 2√3

= (22 + 2)√3

= 24√3

Therefore, a = 24.
