计算log3[(9^2*27^(1/3))/3^(log3234)]计算log3[(9^2*27^(1/3))/3^(log3234)]计算log3[(9^2*27^(1/3))/3^(log3234

计算log3[(9^2 * 27^(1/3))/3^(log3 234)]
计算log3[(9^2 * 27^(1/3))/3^(log3 234)]

计算log3[(9^2 * 27^(1/3))/3^(log3 234)]
[(9^2 * 27^(1/3))/3^(log3 234)]=(9^2 * 27^(1/3))/3^(log3 234)
=(81*3)/(234)
=3^5/234
log3[(9^2 * 27^(1/3))/3^(log3 234)]
=log3(3^5/234)
=5-log3(234)
另外这里是不是243啊 如果是243的话,那就等于
=5-log3(243)
=5-5=0

log3[(9^2 * 27^(1/3))/3^(log3 234)]
=log3[3^4*3^(3*1/3))/3^(log3 (3^2*26)]
=log3[3^5/3^(2+log3 26)]
=log3[3^(5-(2+log3 26)]
=log3 [3^(3-log3 26)]
=3-log3 26
