4)) \( \sqrt{\frac{x}{x}} \), Subtract. \( \frac{7}{10}-\frac{3}{5}=\square \)

Sure, let's tackle each part of the problem step by step. ### 1. Simplifying \( \sqrt{\frac{x}{x}} \) First, simplify the expression inside the square root: \[ \frac{x}{x} = 1 \quad \text{(assuming } x \neq 0\text{)} \] Now, take the square root of 1: \[ \sqrt{1} = 1 \] **So,** \[ \sqrt{\frac{x}{x}} = 1 \] ### 2. Subtracting \(\frac{7}{10} - \frac{3}{5}\) First, ensure both fractions have the same denominator. The second fraction, \(\frac{3}{5}\), can be converted to tenths: \[ \frac{3}{5} = \frac{3 \times 2}{5 \times 2} = \frac{6}{10} \] Now, perform the subtraction: \[ \frac{7}{10} - \frac{6}{10} = \frac{1}{10} \] **So,** \[ \frac{7}{10} - \frac{3}{5} = \frac{1}{10} \] ### **Final Answers:** 1. \( \sqrt{\frac{x}{x}} = 1 \) 2. \( \frac{7}{10} - \frac{3}{5} = \frac{1}{10} \)
