化简 ((1410^9))/((210^3))

解答

化简

\frac{( 14 \cdot 1 0 ^{9} )}{( 2 \cdot 1 0 ^{3} )}

7000000

求解步骤

\frac{14 \cdot 1 0 ^{9}}{2 \cdot 1 0 ^{3}}

\frac{1 0 ^{9}}{1 0 ^{3}} = 1 0^{6}

= \frac{14 \cdot 1 0 ^{6}}{2}

数字相除:

\frac{14}{2} = 7

= 7 \cdot 1 0^{6}

7 \cdot 1 0^{6} = 7000000

= 7000000

0 = x^{2} - 10 x + 25

s im pl i f y (- \frac{9}{2})^{2}

\frac{( 3 x + 3 )}{2 x - 4} < 0
