\(\frac{9^7.2^3-3^{14}.4}{3^{17}-3^{15}.5}\)

\(=\frac{\left(3^2\right)^7.2^3-3^{14}.2^2}{3^{15}.\left(3^2-5\right)}\)

\(=\frac{3^{14}.2^3-3^{14}.2^2}{3^{15}.\left(9-5\right)}\)

\(=\frac{3^{14}.2^2.\left(2-1\right)}{3^{15}.2^2}\)

\(=\frac{1}{3}\)

3/6.25=1/2.25=1/50

thanks

3 / 6,25=0,48

3 / 6.25=3/150=1/50

\(\dfrac{5^6.25^3}{25}=\dfrac{5^6.5^6}{5^2}=5^{6+6-2}=5^{10}\)

\(\dfrac{5^6.25^3}{25}=\dfrac{5^6.\left(5^2\right)^3}{5^2}=\dfrac{5^6.5^6}{5^2}=\dfrac{5^{12}}{5^2}=5^{12-2}=5^{10}\)

\(\dfrac{5^6.25^3}{25}\)\(=5^6.25^2=9765625\)

( 29,38 - 3,25 x 5 +36,36 : 3 ) : 6,25

= 25,25 : 6,25

=  4,04

Dấu soa là gì vậy bạn

cau nay bang 4,04 nha

dễ 4,04

(29,38-3,25*5+36,36/3)/6,25=4,04

4,04

chúc bạn học giỏi

đáp án là 4.04 bạn ơi
