Question

2.3+(−1.478)(0) -0 is an exponent
GPT-4o mini
To simplify the expression \(2.3 + (-1.478)(0) - 0\):

1. Calculate \((-1.478)(0)\), which equals \(0\).
2. Now substitute this back into the expression:

\[
2.3 + 0 - 0
\]

This simplifies to:

\[
2.3
\]

Thus, the result is \(2.3\).
2.3+(−1.478)0
zero is an exponent

Ah, I see! You are expressing that the zero is an exponent. So the expression is:

\[
2.3 + (-1.478)^0
\]

According to the rules of exponents, any non-zero number raised to the power of 0 is 1. Therefore:

\[
(-1.478)^0 = 1
\]

Now substituting this back into the expression:

\[
2.3 + 1
\]

This simplifies to:

\[
3.3
\]

So the final answer is \(3.3\).
-40⋅15
the zero is the exponent

It seems there might be a small misunderstanding in the notation. If your expression is meant to indicate that the zero is an exponent pertaining to the number 15, it would be written as:

\[
-40 \cdot 15^0
\]

According to the rules of exponents, any non-zero number raised to the power of 0 equals 1. Hence:

\[
15^0 = 1
\]

Now, substituting this back into the expression gives:

\[
-40 \cdot 1 = -40
\]

So, the final answer is \(-40\).
*not 40 4^0

Thank you for the clarification! If the expression is \(-4 \cdot 4^0\), we can simplify it as follows:

According to the rules of exponents, any non-zero number raised to the power of 0 is 1. Therefore:

\[
4^0 = 1
\]

Now, substituting this back into the expression gives:

\[
-4 \cdot 1 = -4
\]

Thus, the final answer is \(-4\).
