化简 (5(3)^2)/2-((3)^3)/3

解答

化简

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

\frac{27}{2}

十进制

13.5

求解步骤

\frac{5 \cdot 3 ^{2}}{2} - \frac{3 ^{3}}{3}

\frac{5 \cdot 3 ^{2}}{2} = \frac{45}{2}

\frac{3 ^{3}}{3} = \frac{27}{3}

= \frac{45}{2} - \frac{27}{3}

\frac{45}{2} - \frac{27}{3} = \frac{27}{2}

= \frac{27}{2}

9 p^{2} - 8 = - 7
