\(\frac{15^3}{27}\)

TÍNH GIÚP  MÌNH NHA 

Answer 1

\(\frac{72^2}{24^2}=\frac{\left(2^3\cdot3^2\right)^2}{\left(2^3\cdot3\right)^2}=\frac{2^6\cdot3^4}{2^6\cdot3^2}=3^2=9\)

\(\frac{15^3}{27}=\frac{3^3\cdot5^3}{3^3}=5^3=125\)

Answer 2

72^2/24^2 = (72/24)^2 = 3^2 = 9

15^3/27 = 15^3/3^3 = (15/3)^3 = 5^3 = 125

Answer 3

\(\frac{72^2}{24^2}=\left(\frac{72}{24}\right)^2=3^2=9\)

\(\frac{15^3}{27^3}=\frac{15^3}{3^3}=\left(\frac{15}{3}\right)^3=5^3=125\)

Answer 4

\(\frac{72^2}{24^2}=\frac{2^6.3^4}{2^6.3^2}\)\(=\frac{3^4}{3^2}=3^2=9\)

\(\frac{15^3}{27}=\frac{\left(3.5\right)^3}{3^3}=\frac{3^3.5^3}{3^3}=5^3=125\)
