Final answer:
To determine 8√x using a calculator, enter x, press the square root key, then multiply by 8. Ensure the order of operations is followed for accuracy. For higher roots, use appropriate fractional powers on calculators that support these functions.
Step-by-step explanation:
To calculate the expression 8√x using a calculator, you should first enter the value of x, then press the square root key (often labeled as √ or sqrt), which will compute the square root of x. After obtaining the square root, multiply the result by 8 to get the final answer. It's important to follow this order of operations to ensure the accuracy of the answer. In case your calculator allows entry of the equation as it is written, you can input 8, followed by the multiplication key, and then the square root of x; however, this method usually requires a calculator that supports algebraic operations and understands the precedence of operations.
If you are dealing with more complex operations, like cube roots or higher orders, you may need to raise the number to the appropriate fractional power, which can typically be done using a y* or xy button and entering the fractional exponent equivalent to the root desired, for example, 0.5 for square root or 0.25 for fourth root.
