Use a calculator to evaluate the following exponential expression. Round to two decimal places.
$7^{1.3}$

• A. $12.14$
• B. $12.55$
• C. $13.24$
• D. $11.75$

Answer: (B)

Verified step by step guidance

1. Identify the expression to evaluate: \$7^{1.3}$. This means 7 raised to the power of 1.3.
2. Understand that the exponent 1.3 is a decimal, so this is an example of an exponential expression with a non-integer exponent.
3. Use a calculator to compute \$7^{1.3}$. Most scientific calculators have a power function, often labeled as \(x^y\) or similar.
4. Enter 7, then use the power function key, and then enter 1.3 to calculate the value of \$7^{1.3}$.
5. After obtaining the result from the calculator, round the answer to two decimal places as requested.
