Answer»

Given expression:

Follow BODMAS rule to solve this question, as PER the order is given below,$

Step - 1 - $Parts of an equation ENCLOSED in 'Brackets' must be solved first,$

Step - 2 - $Any mathematical 'Of' or 'Exponent' must be solved next,$

Step - 3 - $Next, the parts of the equation that contains 'Division' and 'Multiplication' are calculated,$

Step - 4 - $Last but not least, the parts of the equation that contains 'Addition' and 'Subtraction' should be calculated.$

$(3\FRAC{6}{{17}} \div 2\frac{7}{{34}} - 1\frac{9}{{25}} = {\LEFT( ? \right)^2})$

$(\Rightarrow {\left( ? \right)^2} = \frac{{57}}{{17}} \div \frac{{75}}{{34}} - \frac{{34}}{{25}})$

$(\Rightarrow {\left( ? \right)^2} = \frac{{57}}{{17}} \times \frac{{34}}{{75}} - \frac{{34}}{{25}})$

$(\Rightarrow {\left( ? \right)^2} = \frac{{38}}{{25}} - \frac{{34}}{{25}} = \frac{4}{{25}})$
