Zero Power Rule of Exponents Practice
Math 8 Q2 (Pre-Algebra) / Exponent Rules

Apply the Zero Power Rule of Integer Exponents to solve 2.3 + (-1.478)

Answer 1

The Zero Power Rule of Exponents states that any non-zero number raised to the power of zero is equal to 1. However, in the expression you provided, \(2.3 + (-1.478)\), there are no exponents to apply the Zero Power Rule directly.

Instead, let's solve the expression arithmetic-wise:

\[
2.3 + (-1.478) = 2.3 - 1.478
\]

Now, perform the subtraction:

Subtracting \(1.478\) from \(2.3\):

1. Align the decimal points:
```
2.300
- 1.478
--------
```

2. Perform the subtraction:
- From the thousandths: \(0 - 8\) (we need to borrow)
- From the hundredths: \(0 - 7\) (again, we need to borrow)
- From the tenths: \(3 - 4\) (also need to borrow)

After careful borrowing and adjusting, you will find:

\[
2.3 - 1.478 = 0.822
\]

Thus,

\[
2.3 + (-1.478) = 0.822
\]
