Question

simplify 8.5x8.5 - 5.5x 5.5​

Answer 1

• As per the data given in the question, we have to find the value of the expression.

         Given data:- $8.5\times8.5-5.5\times5.5$

          To find:- The value of the expression.

         Solution:-

• To solve the above equation we will follow the BODMAS rule.
• It is the rule used to remember the order of operations to be followed while solving expressions in mathematics.
• where,

           $\\B=bracket\\\mathrm{O}=\text {order of powers or rules } \\\mathrm{D}=\text {division } \\\mathrm{M}=\text {multiplication } \\\mathrm{A}=\text {addition } \\\mathrm{S}=\text {subtraction }\end{array}$

• By using the  BODMAS rule,

          $8.5\times8.5-5.5\times5.5\\=72.25-30.25\\=42.$

      Hence $8.5\times8.5-5.5\times5.5$ is equal to $42.$

Answer 2

Answer:

$8.5\times 8.5-5.5\times 5.5=42$.

Step-by-step explanation:

Given $8.5\times 8.5-5.5\times 5.5$.

For computing any calculation, we use the BODMAS rule.

B - Brackets

O - Orders

D - Division

M - Multiplication

A - Addition

S - Subtraction

First compute the multiplication and then subtract the values.

$8.5\times 8.5-5.5\times 5.5$

$=72.25-30.25$

$=42$.
