[tex]\( 3 \times 11 = 33 \)[/tex]
Thus, [tex]\( 3 \sqrt{121} = 33 \)[/tex].
### Expression 4: [tex]\( 3 \sqrt{14^2} \)[/tex]
1. Calculate the square root of [tex]\( 14^2 \)[/tex].
[tex]\( \sqrt{14^2} = 14 \)[/tex]
2. Now, multiply the result by 3.
[tex]\( 3 \times 14 = 42 \)[/tex]
Thus, [tex]\( 3 \sqrt{14^2} = 42 \)[/tex].
### Expression 5: [tex]\( 3 \sqrt{11^3} \)[/tex]
1. Calculate [tex]\( 11^3 \)[/tex].
[tex]\( 11^3 = 1331 \)[/tex]
2. Calculate the square root of 1331. Note that [tex]\( 11^3 \)[/tex] can also be written as [tex]\( 11^{3/2} \)[/tex].
[tex]\( \sqrt{1331} = 36.4828726939094 \)[/tex]
4. Now, multiply the result by 3.
[tex]\( 3 \times 36.4828726939094 = 109.4486180817282 \)[/tex]
Thus, [tex]\( 3 \sqrt{11^3} \approx 109.4486180817282 \)[/tex].
