Answer 2

To evaluate the expression 0.9a^(5/6) : 3a^(1/3) when a = 16, we substitute the value of a into the expression:

0.9(16^(5/6)) : 3(16^(1/3))

Now let's simplify each term:

16^(5/6) can be calculated as the sixth root of 16 raised to the power of 5. Since 16 is a perfect square, we can simplify it further:

16^(5/6) = (16^(1/6))^5 = 2^5 = 32

16^(1/3) can be calculated as the cube root of 16, which is 2.

Now let's substitute these values back into the expression:

0.9(32) : 3(2)

Simplifying further:

28.8 : 6

Dividing 28.8 by 6 gives us:

4.8

Therefore, when a = 16, the value of the expression 0.9a^(5/6) : 3a^(1/3) is 4.8.
