Answer 2

The value $\sqrt{0.00002809}$ = 0.0053

Step-by-step explanation:

We have,

$\sqrt{0.00002809}$

To find, the value $\sqrt{0.00002809}$ = ?

∴ $\sqrt{0.00002809}$

$=\sqrt{\dfrac{2809}{100000000} }$

= $\sqrt{\dfrac{53\times 53}{10^8} }$

= $\sqrt{\dfrac{53\times 53}{(10^4)^2} }$

Using the exponential identity,

$(a^{m})^n=a^{mn}$

= $\dfrac{53}{10000}$

= 0.0053

∴ The value $\sqrt{0.00002809}$ = 0.0053

Thus, the value $\sqrt{0.00002809}$ = 0.0053
