Understand the Problem
The question is asking to perform various radical operations to decode a message. Each operation results in a numerical or variable expression that needs to be matched with a corresponding word or phrase from the instructions.
Answer
The values decoded are \( \frac{\sqrt{5}}{2}, 7, 36, 6, 3x^4y^3\sqrt{g}, 10\sqrt{3}a^{3/2}, 9 \).
Answer for screen readers
The answers corresponding to the radical calculations are:
- ( \frac{\sqrt{5}}{2} )
- ( 7 )
- ( 36 )
- ( 6 )
- ( 3x^4y^3\sqrt{g} )
- ( 10\sqrt{3}a^{3/2} )
- ( 9 )
Steps to Solve
- Calculate ( \sqrt{2} \cdot \sqrt{5/8} )
First, multiply the square roots: $$ \sqrt{2} \cdot \sqrt{5/8} = \sqrt{2 \cdot \frac{5}{8}} = \sqrt{\frac{10}{8}} = \sqrt{\frac{5}{4}} = \frac{\sqrt{5}}{2} $$
- Calculate ( \sqrt{7} \cdot \sqrt{7} )
Next, simplify: $$ \sqrt{7} \cdot \sqrt{7} = 7 $$
- Calculate ( 4\sqrt{3} \cdot 3\sqrt{3} )
Now, multiply: $$ 4\sqrt{3} \cdot 3\sqrt{3} = 12 \cdot 3 = 36 $$
- Calculate ( \sqrt{9} \cdot \sqrt{4} )
Then, simplify: $$ \sqrt{9} \cdot \sqrt{4} = 3 \cdot 2 = 6 $$
- Calculate ( \sqrt{gxy^2} \cdot \sqrt{3} \cdot \sqrt{3x^6} )
Combine the square roots: $$ \sqrt{g \cdot x^2 \cdot 3 \cdot 3x^6} = \sqrt{9x^8y^6g} = 3x^4y^3\sqrt{g} $$
- Calculate ( \left(\sqrt{5a}\right) \cdot \left(\sqrt{2}\right) \cdot \left(\sqrt{30a^2}\right) )
Now compute: $$ \sqrt{5a} \cdot \sqrt{2} \cdot \sqrt{30a^2} = \sqrt{5a \cdot 2 \cdot 30a^2} = \sqrt{300a^3} = 10\sqrt{3}a^{3/2} $$
- Calculate ( \sqrt{27} \cdot \sqrt{3} )
Lastly, simplify: $$ \sqrt{27} \cdot \sqrt{3} = \sqrt{81} = 9 $$
The answers corresponding to the radical calculations are:
- ( \frac{\sqrt{5}}{2} )
- ( 7 )
- ( 36 )
- ( 6 )
- ( 3x^4y^3\sqrt{g} )
- ( 10\sqrt{3}a^{3/2} )
- ( 9 )
More Information
Each radical operation corresponds to a number or expression that conveys a specific meaning in the message. The resulting values can be used to decipher the phrase hidden in the activity.
Tips
