14

Answer 2

To find : $10 \div (20\div 2^{2}\times 5\div 5 ) \times 8-2$

• To solve the above equation we will follow BODMAS rule.

• It is the rule used to remember the order of operations to be followed while solving expressions in mathematics.

• where,  

                $\begin{array}{l} \\B=brackets \\\mathrm{O}=\text { order of powers or rules } \\\mathrm{D}=\text { Division } \\\mathrm{M}=\text { multiplication } \\\mathrm{A}=\text { addition } \\\mathrm{S}=\text { subtraction }\end{array}$

• According to above rule we will solve .
• $10 \div (20\div 2^{2}\times 5\div 5 ) \times 8-2$  

        $= 10 \div ( \frac{20}{4} \times \frac{5}{5} )\times 8-2 \\= 10\div (5\times 1 ) \times 8 -2 \\= 10 \div 5 \times 8-2 \\=\frac{10}{5}\times 8-2 \\= 2\times 8-2 \\=16-2 \\=14$

Hence , value of given expression $14$ .
