Simplify the square root (Picture provided)
Elodia [21]

For this case we must find the value of the following expression:

\sqrt {8 ^ {17}}

We have to:

8 ^ {17} = 8 ^ 1 * 8 ^ {16}

Substituting:

\sqrt {8 * 8 ^ {16}}

By definition of properties of powers and roots we have:

\sqrt [n] {a ^ m} = a ^ {\frac {m} {n}}

So:

8 ^ {\frac {16} {2}} * \sqrt {8}\\8 ^ 8 * \sqrt {8}

So we have to:

\sqrt {8 ^ {17}} = 8 ^ 8 * \sqrt {8}

Answer:

8 ^ 8 * \sqrt {8}

Option A

Use index form. N= a^x becomes log a (N) = x
Therefore your question becomes (log 2.3 (13))/9 = x
And rounding to 3 decimals gives you 0.342
