      \(\frac{27.2^{10}.3^9.32}{6^{12}}\)

\(=\frac{3^3.2^{10}.3^9.2^5}{\left(2.3\right)^{12}}\)

\(=\frac{3^{12}.2^{15}}{2^{12}.3^{12}}=2^3=8\)

\(\dfrac{0.375-0.3+\dfrac{3}{11}+\dfrac{3}{12}}{-0.625+0.5-\dfrac{5}{11}-\dfrac{5}{12}}+\dfrac{1.5+1-0.75}{2.5+\dfrac{5}{3}-1.25}\)

=\(\dfrac{\dfrac{3}{8}-\dfrac{3}{10}+\dfrac{3}{11}+\dfrac{3}{12}}{-\dfrac{5}{8}+\dfrac{5}{10}-\dfrac{5}{11}-\dfrac{5}{12}}+\dfrac{\dfrac{3}{2}+\dfrac{3}{3}-\dfrac{3}{4}}{\dfrac{5}{2}+\dfrac{5}{3}-\dfrac{5}{4}}\)

=\(\dfrac{3.\left(\dfrac{1}{8}-\dfrac{1}{10}+\dfrac{1}{11}+\dfrac{1}{12}\right)}{-5.\left(\dfrac{1}{8}-\dfrac{1}{10}+\dfrac{1}{11}+\dfrac{1}{12}\right)}+\dfrac{3\cdot\left(\dfrac{1}{2}+\dfrac{1}{3}-\dfrac{1}{4}\right)}{5\cdot\left(\dfrac{1}{2}+\dfrac{1}{3}-\dfrac{1}{4}\right)}\)

=3.5=15

\(\frac{4^{15}.3^{12}+120.8^3}{2^3.3^9-27.2^4}\)

\(=\frac{2^{30}.3^{12}+2^3.3.5.2^9}{2^3.3^9-3^3.2^4}\)

\(=\frac{2^{30}.3^{12}+2^{12}.3.5}{2^3.3^3\left(3^6-2\right)}\)

\(=\frac{2^{12}.3\left(2^8.3^{11}+5\right)}{2^3.3^3.727}\)

\(=\frac{2^9\left(2^8.3^{11}+5\right)}{3^2.727}\)

đến đây dễ rồi bạn tự làm đi

thank you

27.2+27.8+2.3

=27.(8+2)+6

=27.10+6

=270+6

=276

27 . 2³ + 4 . 3² - 5 . 12⁰

= 27 . 8 + 4 . 9 - 5 . 1

= 216 + 36 - 5

= 252 - 5

= 247

\(27.2^3+4.3^2-5.12^0\)

\(=27.8+4.9-5.1\)

\(=216+36-5\)

\(=247\)
