Question

Rút gọn biểu thức : A = 2^15 . 3^12 - 3^11. 2^17 / 2^15.3^11+3^11. 2^17

I don't need you · Accepted Answer

$A=\frac{2^{15}.3^{12}-3^{11}.2^{17}}{2^{15}.3^{11}+3^{11}.2^{17}}$

$A=\frac{2^{15}.3^{11}.\left(3-2^2\right)}{2^{15}.3^{11}.\left(1+2^2\right)}$

$A=\frac{3-2^2}{1+2^2}$

$A=\frac{-1}{5}$

Câu trả lời:

$A=\frac{2^{15}.3^{12}-3^{11}.2^{17}}{2^{15}.3^{11}+3^{11}.2^{17}}$

$A=\frac{2^{15}.3^{11}.\left(3-2^2\right)}{2^{15}.3^{11}.\left(1+2^2\right)}$

$A=\frac{3-2^2}{1+2^2}$

$A=\frac{-1}{5}$
