The correct Answer is:
To solve the problem step by step, we will find the value of \( \frac{1}{\sqrt{3} - \sqrt{2}} \) using the given approximations \( \sqrt{2} = 1.4 \) and \( \sqrt{3} = 1.7 \). ### Step 1: Write the expression We start with the expression: \[ \frac{1}{\sqrt{3} - \sqrt{2}} \] ### Step 2: Substitute the values of \( \sqrt{2} \) and \( \sqrt{3} \) Substituting the given values: \[ \frac{1}{1.7 - 1.4} \] ### Step 3: Simplify the denominator Now, we simplify the denominator: \[ 1.7 - 1.4 = 0.3 \] So, we have: \[ \frac{1}{0.3} \] ### Step 4: Calculate the value Now, we calculate \( \frac{1}{0.3} \): \[ \frac{1}{0.3} = \frac{10}{3} \approx 3.3333 \] ### Step 5: Round to one decimal place Finally, we round \( 3.3333 \) to one decimal place: \[ 3.3 \] ### Final Answer Thus, the value of \( \frac{1}{\sqrt{3} - \sqrt{2}} \) correct to one decimal place is: \[ \boxed{3.3} \]
