Question

Evaluate 3.2(b=2), when b= 2 1) 0.8 2) 3.2 3) 12.8 4) 13.8

Answer 1

The value of
`\(3.2 * (b=2)\)` when
`\(b = 2\)` is
`\( \mathbf{2) \ 3.2} \).`

Step-by-step explanation:

To evaluate the expression
`\(3.2 * (b=2)\)` when
`\(b = 2\)` , we substitute the value of
`\(b\)` into the expression:

`\[ 3.2 * (2=2) \]`

The expression
`\(2=2\)` evaluates to true, which is equivalent to 1. Therefore, the expression simplifies to:

`\[ 3.2 * 1 = 3.2 \]`

Hence, the correct answer is
`\(3.2\)`, and option 2) accurately represents this value.

Understanding how to substitute values into expressions and perform basic arithmetic operations is fundamental in mathematics.

In this case, recognizing that the expression
`\(b=2\)` evaluates to 1 allows for the straightforward evaluation of the entire expression. Such skills are essential in various mathematical applications, from algebraic manipulations to solving real-world problems that involve mathematical expressions and calculations.

In conclusion, the expression
`\(3.2 * (b=2)\)` simplifies to
`\(3.2\)`, and the accurate representation of this value is option 2) in the given choices. This demonstrates the importance of numerical understanding and manipulation in obtaining correct solutions to mathematical expressions.
