解題步驟

識別所有運算式的所有因數與其最高乘冪。將這些因數的最高乘冪相乘以取得最小公倍數。

$$t\left(268435456x^{14}[phone]x^{7}y^{7}[phone]x^{6}y^{8}+2050048x^{5}y^{9}+256256x^{4}y^{10}+23296x^{3}y^{11}+1456x^{2}y^{12}+56xy^{13}+y^{14}[phone]y^{6}x^{8}[phone]y^{5}x^{9}[phone]y^{4}x^{10}[phone]y^{3}x^{11}[phone]y^{2}x^{12}[phone]yx^{13}\right)$$
