Evaluate the following fractional or decimal expression. ( − 0.6 ) 2 \left(-0.6\right)^2

we're asked to evaluate the following fractional or decimal expression. Here we're given an expression with a decimal negative 0.6 squared. Now, because I know that exponents represent repeated multiplication, that is no different when working with a decimal. So this tells me that I want to take negative 0.6 and multiply it by itself. So that's negative point six times negative point six. Now when I do this multiplication here, this will give me a positive because a negative times a negative gives me a positive. And this is gonna be 0.36. Now when working with exponential expressions that have a negative base like this one, we always wanna check back to make sure we got our sign right. So looking at that power here, it is an even value, which means I would expect my final answer to be positive, and here it is. Let us know if you have any questions, and I'll see you in the next one.

Identify the base and the exponent in the given exponential expression. Since the problem involves negative bases, pay close attention to whether the base is enclosed in parentheses or not, as this affects the sign of the result.

Recall the rule that when a negative number is raised to an even exponent, the result is positive, and when raised to an odd exponent, the result is negative. This is because multiplying an even number of negative factors results in a positive product, while an odd number results in a negative product.

Rewrite the expression clearly, for example, if the expression is $(-a)^n$, keep the parentheses to indicate the negative base is raised to the power $n$. If the expression is $-a^n$, note that only $a$ is raised to the power $n$, and the negative sign is applied afterward.

Calculate the absolute value of the base raised to the exponent, which means computing $a^n$ without considering the sign. This step focuses on the magnitude of the number.

Apply the sign determined in step 2 to the result from step 4. If the exponent is even, the result is positive; if odd, the result is negative. This completes the evaluation of the exponential expression with a negative base.
