Chapter B, Problem 1E

To determine

The solution for the expression.

Answer to Problem 1E

Solution:

The solution for the expression is $3.09$.

Explanation of Solution

Given:

The expression is,

$3.27-0.1834$

Approach:

The significant figures in a number are the ones from first nonzero digit to the last nonzero digit when reading from left to right.

When adding or subtracting, round off the final result so that it has its last significant digit in the decimal place in which the least accurate given value has its last significant digit.

Calculation:

Evaluate the expression.

$\begin{array}{rll}3.27-0.1834& =& 3.0866\\ & \approx & 3.09\end{array}$

Therefore, the solution for the expression is $3.09$.

Conclusion:

Hence, the solution for the expression is $3.09$.
