化简 ((1/3)^2+3)(5-1/3)

解答

化简

((\frac{1}{3})^{2} + 3) (5 - \frac{1}{3})

\frac{392}{27}

十进制

14.51851 \dots

求解步骤

((\frac{1}{3})^{2} + 3) (5 - \frac{1}{3})

化简

(\frac{1}{3})^{2} + 3 : \frac{28}{9}

= \frac{28}{9} (5 - \frac{1}{3})

5 - \frac{1}{3} = \frac{14}{3}

= \frac{28}{9} \cdot \frac{14}{3}

\frac{28}{9} \cdot \frac{14}{3} = \frac{392}{27}

= \frac{392}{27}

s im pl i f y 6 (\frac{3}{2})

4^{2} + 5^{2} = 6^{2}

6 x - 15 > - 45

f a c t or 10 x^{3} - 20 x^{2} - 2 x + 4

h^{2} = 2^{2} + 2^{2}
