Question

(-2)²-(-1/3)²:4²+(-1/2)²

Answer 1

4  - 0,37 / 16 + 0,25
3,63 / 16,25 = 0,2234

Answer 2

${( - 2})^{2} - ( { \frac{ - 1}{3} })^{2} \div {4}^{2} + ({ \frac{ - 1}{2} })^{2} = \\ = 4 - \frac{ 1}{9} \times \frac{1}{16} + \frac{1}{4} = \\ = 4 - \frac{1}{144} + \frac{1}{4} = \\ = \frac{575}{144} - \frac{1}{144} + \frac{36}{144} = \frac{610}{144} \\ = \frac{305}{72}$
