Answer 1

Answer:

(2)(-1)²+(2)²(-1)

-2

Step-by-step explanation:

Answer 2

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

           Given data:- $(2)(-1)^2+(2)^{2} (-1).$

           To find:- Value of above expression.

            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

      Therefore,

      $(2)(-1)^2+(2)^{2} (-1)\\=>(2)(1)+4(-1)\\=>2+-4\\=>-2.$

      Hence we will get the value is $-2.$
