Question

Evaluate the expression for the given value of the variable. $$5 x^{2} \text { when } x=0.3$$

Short answer

The evaluated result of the expression is 0.45

Step-by-step solution

- Identify the given expression and the variable

The given expression is \(5x^2\) and the variable \(x\) is given as 0.3

- Substitute the given value into the expression

We will replace \(x\) in the expression with 0.3. So it will become \(5 * (0.3)^2\)

- Evaluate the expression

Now, we have to compute the expression \(5 * (0.3)^2\). First calculate the square of 0.3, which equals 0.09, and then multiply by 5, yielding 0.45
