计算log550+og52.5=?要过程啊计算log550+og52.5=?要过程啊计算log550+og52.5=?要过程啊log550+log52.5=log5(50x2.5)=log5125=l

计算log5 50+og5 2.5=?要过程啊
计算log5 50+og5 2.5=?
要过程啊

计算log5 50+og5 2.5=?要过程啊
log5 50+log5 2.5
=log5 (50x2.5)
=log5 125
=log5 5^3
=3

=log5 (50*2.5)=log5 5^3=3

log5 50+log5 2.5
=log5 (50*2.5)
=log5 (125)
=3
