Question

1/3√900y - √121y = ?

Answer 1

1/3√900y-√121y=1/3×30√y-11√y=10√y-11√y=-√y

Answer 2

To solve the expression, let's simplify it step by step:

1. 1/3√900y: First, find the cube root of 900y, which is ∛(900y) = ∛(27 * 33 * y) = 3∛(100 * y) = 3 * 10∛y. Now, multiply by 1/3: 1/3 * (3 * 10∛y) = 10∛y.

2. √121y: The square root of 121y is √(121 * y) = √(121) * √(y) = 11√y.

Now, the expression becomes: 10∛y - 11√y.

This is the final simplified expression, and it cannot be simplified any further unless you provide a specific value for 'y' to get a numerical answer.
