Question

Hi all plz help
If a= 2, b= -2, find the answer of
a²+b²

Answer 1

Answer:

Hi

In this question we will use the BODMAS rule

Put= a= 2, b = -2

= (2)²+(-2)²

= 4+4

= 8

Answer 2

• We have to evaluate the above expression by using the given data.

              Given data:- $a=2,b=-2.$

              To find:- Value of above expression $a^{2} +b^{2} .$

              Solution:-

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

• BODMAS is an order of mathematic operations.

• BODMAS rule is to be followed while solving expressions in mathematics. It stands for,

          B= bracket

           O= order of power or rules

           D= division

           M= multiplication

           A= addition

           S= subtraction

         Now put the value a and b in the given equation we get,

              $a^{2} +b^{2} \\=>(2)^{2} +(-2)^2\\=>4+4\\=>8.$

      Hence we will get the value is $8.$
