Question

√3=1.732 find the value of√75+1/2√48-√198​

Answer 1

Answer:

12.124-3$\sqrt{22}$

Step-by-step explanation:

$\sqrt{75} = \sqrt{5^{2}*3}$

$\sqrt{48}= \sqrt{2^{2}*2^{2}*3}$

$\sqrt{198} =\sqrt{3^{2}*2*11}$

$\sqrt{75} +\frac{1}{2} *\sqrt{48} - \sqrt{198} \\\\\sqrt{5^{2}*3} +\frac{1}{2} *\sqrt{2^{2}*2^{2}*3} - \sqrt{3^{2}*2*11} \\\\5\sqrt{3} +\frac{1}{2} *4 \sqrt{3} - 3 \sqrt{2*11} \\\\5\sqrt{3} +2 \sqrt{3} - 3 \sqrt{22} \\\\5*1.732 +2*1.732 - 3 \sqrt{22} \\\\8.66 + 3.464 - 3 \sqrt{22}\\\\12.124- 3 \sqrt{22}$
