Question

Which expression is the exponential form of /9y ?

Answer 1

(C)
`(9y)^{(1)/(2)}`

Explanation:

The given expression is:

`√(9y)`

Upon solving the above given expression, we have the expression can be written as:

`\sqrt{9{\cdot}y}`

`(9y)^{(1)/(2)}`

which is the required expression in the exponential form of
`√(9y)`.

The above can further be also simplified as:

`\sqrt{9{\cdot}y}`

`√(3^2y)`

`3{√(y)`

Hence, option (C) is correct.

Answer 2

For this case we have the following expression:
root (9y)
We can in this case use the properties of the power to write the expression in an equivalent way
Rewriting we have:
(9y) ^ (1/2)
Answer:
(9y) ^ (1/2)
