$2.4 \times 10^{6}$ $2.4xx10^6$

Explanation:

$R = \frac{{(3.8 \times 10^{5})}^{2}}{5.9 \times 10^{4}}$ $R=((3.8xx10^5)^2)/(5.9xx10^4)$

$R = \frac{14.44 \times 10^{10}}{5.9 \times 10^{4}}$ $color(white)(R)=(14.44xx10^(10))/(5.9xx10^4$

$R = \frac{14.44}{5.9} \times 10^{(10 - 4)}$ $color(white)(R)=14.44/5.9xx10^((10-4))$

$R = 2.447 . . \times 10^{6}$ $color(white)(R)=2.447..xx10^6$

Since the initial values given for x and y are to 1 decimal place it would be appropriate to return the answer to 1 decimal place.

$\Rightarrow \approx 2.4 \times 10^{6} \to to 1 decimal place$ $rArr~~2.4xx10^6rarr" to 1 decimal place"$
