√1.69-1.44 our options is 5,0.5,0.05,0.005​

Answer 1

Answer:

$\sqrt{1.69-1.44}=0.5$

Step-by-step explanation:

$\sqrt{1.69-1.44}\\=\sqrt{(1.3)^{2}-(1.2)^{2}}\\=\sqrt{(1.3+1.2)(1.3-1.2)}\\=\sqrt{2.5\times 0.1}\\=\sqrt{0.25}\\=\sqrt{(0.5)^{2}}\\=0.5$

Therefore,

$\sqrt{1.69-1.44}=0.5$

Or

$\sqrt{1.69-1.44}\\=\sqrt{0.25}\\=\sqrt{(0.5)^{2}}\\=0.5$
