The Correct Answer and Explanation is:
To convert ( 8\left(\frac{2}{3}\right) ) into radical form and simplify it to an integer, we can follow these steps:
Step 1: Rewrite the Expression
First, express ( 8 ) as a fraction:
[
8\left(\frac{2}{3}\right) = \frac{8}{1} \times \frac{2}{3}
]
Step 2: Multiply the Fractions
Next, multiply the fractions:
[
\frac{8 \times 2}{1 \times 3} = \frac{16}{3}
]
Step 3: Convert to Radical Form
To express ( \frac{16}{3} ) in radical form, we want to express it as a square root:
[
\frac{16}{3} = \frac{16}{3} \cdot \frac{3}{3} = \frac{48}{9}
]
Now we can take the square root of the numerator and denominator:
[
\sqrt{\frac{48}{9}} = \frac{\sqrt{48}}{\sqrt{9}} = \frac{\sqrt{48}}{3}
]
Step 4: Simplify the Square Root
To simplify ( \sqrt{48} ):
- Factor ( 48 ): ( 48 = 16 \times 3 = 4^2 \times 3 ).
- Apply the square root:
[
\sqrt{48} = \sqrt{16 \times 3} = \sqrt{16} \cdot \sqrt{3} = 4\sqrt{3}
]
Step 5: Substitute Back
Now substitute back into the expression:
[
\frac{\sqrt{48}}{3} = \frac{4\sqrt{3}}{3}
]
Conclusion
At this point, we can recognize that ( \frac{4\sqrt{3}}{3} ) does not yield an integer. However, if the goal is to convert ( 8\left(\frac{2}{3}\right) ) to an integer without radical form, we can simply multiply:
[
8 \cdot \frac{2}{3} = \frac{16}{3} \approx 5.33 \quad \text{(non-integer)}
]
For clarity, if we wanted a precise integer outcome from ( 8 \left( \frac{2}{3} \right) ), we see:
[
\text{Rounded down: } 5
]
Thus, ( 8\left(\frac{2}{3}\right) ) does not simplify to an integer in radical form, yielding a decimal approximately equal to ( 5.33 ). If taken as a whole number, it is simply ( 5 ).
Final Answer:
