Question

if √2=1.414 and√5=2.236 find the value √10-5/2√2 up to three places of decimal

Answer 1

✴Hey mate✴
_______________________

$\frac{ \sqrt{10} - 5 }{2 \sqrt{2} } \times \frac{2 \sqrt{2} }{2 \sqrt{2} } \\ \\ \frac{2 \sqrt{2} ( \sqrt{10} - 5)}{(2 \sqrt{2}) {}^{2} } \\ \\ \frac{4 \sqrt{5} - 10 \sqrt{2} }{8} \\ \\ \frac{\cancel{2 }(2\sqrt{5} - 5 \sqrt{2} )}{ \cancel{8} \: \: {}^{4} } \\ \\ \frac{2 \sqrt{5} - 5 \sqrt{2} }{2}$

On putting the value of √2 = 1.414 and √5 = 2.236

$\frac{2 \sqrt{5} - 5 \sqrt{2} }{4} \\ \\ \frac{2 \times 2.236 - 5 \times 1.141}{2} \\ \\ \frac{4.472 - 5.705}{4} \\ \\ \frac{ - 1.233}{4} = - 305.75$
