evaluate the expression of (9^1/2) and (9^1/6)

1 answer

To evaluate the expressions \( 9^{1/2} \) and \( 9^{1/6} \), we start by rewriting the base.

  1. Calculate \( 9^{1/2} \): \[ 9^{1/2} = \sqrt{9} = 3 \]

  2. Calculate \( 9^{1/6} \): First, we can express \( 9 \) as \( 3^2 \): \[ 9^{1/6} = (3^2)^{1/6} = 3^{2/6} = 3^{1/3} \] Now, we can compute \( 3^{1/3} \), which is the cube root of 3. Thus, the result is approximately: \[ 3^{1/3} \approx 1.442 \]

In summary:

  • \( 9^{1/2} = 3 \)
  • \( 9^{1/6} \approx 1.442 \) (which is \( 3^{1/3} \))
