(lg2)^2+lg5+lg2乘lg5等于多少?(lg2)^2+lg5+lg2乘lg5等于多少?(lg2)^2+lg5+lg2乘lg5等于多少?(lg2)^2+lg5+lg2乘lg5=[(lg2)^2
(lg2)^2+lg5+lg2乘lg5等于多少?
(lg2)^2+lg5+lg2乘lg5等于多少?
(lg2)^2+lg5+lg2乘lg5等于多少?
(lg2)^2+lg5+lg2乘lg5
=[(lg2)^2+lg2乘lg5]+lg5
=lg2[lg2+lg5]+lg5
=lg2+lg5
=1
(lg2)^2+lg5+lg2乘lg5等于多少?
lg5+lg5*lg2+lg2*lg2
lg2(1+lg5)+(lg5)^2
计算:(lg5)^2 +lg2 *lg5
(lg5)^2+lg5.lg2=
2lg2(lg2+lg5)+2lg5得数
(lg2)^2+lg2*lg5+(lg5)^2=
lg2*lg50+lg5*lg20-2lg5*lg2
(lg5)平方+2*lg5*lg2+(lg2)平方
(lg2)^2+lg5*lg20
(lg2)^2+lg20*lg5
(lg5)^2+lg2*lg50
3+lg5+(lg2)^2
2lg5*lg2=
=(lg5)^2+lg2×lg5+lg2 =lg5×(lg5+lg2)+lg2麻烦问一下,这是咋做的
lg2+lg5-log2(3)乘log3(2)
:(lg5)的2方+lg2乘lg50xiexie
(lg5)平方+2/3lg8+lg5乘lg20+(lg2)平方
