Answer» GIVEN, An expression, a(a²+ a +1)+1. To Find, The simplification of this expression with the value of a = -1. Solution, Given expression = a(a²+ a +1)+1. [Substituting the value of a = -1] = -1(-1² + -1 + 1)+1 In the brackets: → -1² = -1 X -1 = 1 → -1 + 1 GETS CANCELLED as the add UPTO 0. By simplifying, we get it as: -1 x 1 + 1 = -1 + 1 = 0 Therefore by simplifying the expression a(a²+ a +1)+1 with the value of a = -1, we get the answer as 0. BODMAS theorem According to the BODMAS theorem, an expression with all the mathematical operations and brackets should be solved in the order as given below: → Brackets Of → Division → Multiplication → Addition → Subtraction

Answer»

An expression, a(a²+ a +1)+1.

The simplification of this expression with the value of a = -1.

Given expression = a(a²+ a +1)+1.

[Substituting the value of a = -1]

= -1(-1² + -1 + 1)+1

In the brackets:

→ -1² = -1 X -1 = 1

→ -1 + 1 GETS CANCELLED as the add UPTO 0.

By simplifying, we get it as:

-1 x 1 + 1

= -1 + 1

= 0

Therefore by simplifying the expression a(a²+ a +1)+1 with the value of a = -1, we get the answer as 0.
