Question

Evaluate the expression.
1+5÷1^3

Answer 1

To evaluate the expression \( 1 + 5 \div 1^3 \), we follow the order of operations (PEMDAS/BODMAS):

1. **Parentheses/Brackets**
2. **Exponents/Orders**
3. **Multiplication and Division** (from left to right)
4. **Addition and Subtraction** (from left to right)

Let's break down the expression step by step:

1. **Calculate the exponent**:
\[
1^3 = 1
\]

2. **Now substitute back into the expression**:
\[
1 + 5 \div 1
\]

3. **Perform the division**:
\[
5 \div 1 = 5
\]

4. **Substitute back into the expression**:
\[
1 + 5
\]

5. **Finally, perform the addition**:
\[
1 + 5 = 6
\]

Thus, the value of the expression \( 1 + 5 \div 1^3 \) is \(\boxed{6}\).
