Radicals and radicals exponents quick check which of the following is an equivalent expression for 5 and 1/2 over three square root 125 when simplified using exponent properties square root 5 over 5 1 5 with power of zero one is it

1 answer

To find an equivalent expression for \(\frac{5^{1/2}}{3\sqrt{125}}\), we will simplify the expression step by step using exponent properties and radical rules.

  1. Simplify \(\sqrt{125}\) first: \[ \sqrt{125} = \sqrt{25 \cdot 5} = \sqrt{25} \cdot \sqrt{5} = 5\sqrt{5} \]

  2. Now substitute \(\sqrt{125}\) back into the expression: \[ \frac{5^{1/2}}{3\sqrt{125}} = \frac{5^{1/2}}{3(5\sqrt{5})} \]

  3. Combine the terms in the denominator: \[ = \frac{5^{1/2}}{15\sqrt{5}} \]

  4. Rewrite \(\sqrt{5}\) as \(5^{1/2}\): \[ = \frac{5^{1/2}}{15 \cdot 5^{1/2}} \]

  5. Now, cancel \(5^{1/2}\) in the numerator and denominator: \[ = \frac{1}{15} \]

Thus, the simplified expression is \(\frac{1}{15}\).

Now, let’s compare this with the given options:

  • Square root 5 over 5: \(\frac{\sqrt{5}}{5}\)
  • 1: \(1\)
  • 5 with power of zero: \(5^0 = 1\)

Since we found the simplified expression to be \(\frac{1}{15}\), none of the options given (\(\sqrt{5}/5\), \(1\), \(5^0\)) are equivalent to our simplified result.

Hence, none of the provided options are correct. If there are additional options you wish to check, please provide them.
