Question

Use logarithm tables to evaluate 41372 X 0.0168^75.63.

a. 1.27
b. 2.53
c. 3.68
d. 4.72

Answer 1

To evaluate expressions using a scientific calculator, you enter the numbers, multiply or divide as required, use the exponent key for powers of ten, and read off the result in scientific notation.

Step-by-step explanation:

The student is asked to evaluate an expression using logarithm tables, which in modern times would typically be done with a calculator. The expression of interest is 41372 multiplied by 0.0168 raised to the power of 75.63. However, to be consistent with the context of the rest of the question, the response should address how to work out similar expressions using a scientific calculator rather than logarithm tables.

For example, to evaluate the expression a. 456 × (7.4 × 108) using a calculator:

1. Enter 456 into the calculator.
2. Multiply by 7.4.
3. Press the exponent or 'EXP' key, depending on the calculator.
4. Enter 8 to indicate that it's 10 to the power of 8.
5. The result should be displayed in scientific notation on the calculator.

This process would be repeated for each expression the student needs to evaluate.
