$\sqrt{10.24} = 3.2$ $sqrt10.24=3.2$ so it is a rational number.

$\sqrt{10.24}$ $sqrt10.24$

= $\sqrt{\frac{1024}{100}}$ $sqrt(1024/100)$ , as $1024=ul(2xx2)xxul(2xx2)xxul(2xx2)xxul(2xx2)xxul(2xx2)$

= $sqrt(2^10/10^2$

= $2^5/10$

= $32/10$

= $3.2$

The number can be written as a fraction, so it is a rational number.
