Answer 2

13. -   (b)  = (0.25)     14.  (d)   = (0.2)

Step-by-step explanation:

13)  

Simplyfying, $\sqrt{(0.0625)}$

$\sqrt{(0.0625)}   = (0.0625)^{\frac{1}{2} }$

Now, (0.0625) = $(0.25)^{2}$

⇒$\sqrt{(0.0625)}   = (0.25)^{2} \times ^{\frac{1}{2}}$

= (0.25)

14)

$\sqrt{(5^{-2})}$  = $(5^{-2})^{\frac{1}{2} }$

=  $5^{-1}  = \frac{1}{5}$  = 0.2

Hence,

$\sqrt{(5^{-2})}  = 0.2$
