lg5的平方加lg2乘lg50

(lg5)^+lg2xlg50=lg5^+lg2x(lg2+2lg5)=lg5^+lg2^+2lg2lg5=(lg5+lg2)^2=(lg10)^2=1

lg50+lg2*lg5+lg²2=?

原式=lg5+lg10+lg2(lg5+lg2)=lg5+1+lg2lg10=lg5+1+lg2=lg10+1=1+1=2

计算(lg5)^2+lg2·lg50

(lg5)^2+lg2·lg50=(lg5)^2+lg2*lg2*25=(lg5)^2+lg2*(lg2+lg25)=(lg5)^2+(lg2)^2+lg2*lg5^2=(lg5)^2+2lg2lg5

计算:lg2+lg5-lg8/lg50-lg40

对数的运算性质如果a>0,a≠1,M>0,N>0,那么(1)loga(MN)=logaM+logaN.(2)logaM/N=logaM-logaN.(3)logaM^n=nlogaM(n∈R).===

(lg5)2+lg2×lg50要过程

(lg5)^2+lg2×lg50=(lg5)^2+lg2×(lg5+lg10)=(lg5)^2+lg2×(lg5+1)=(lg5)^2+lg2×lg5+lg2=lg5×(lg5+lg2)+lg2=lg

(lg5)的平方+lg2*lg50=多少?

lg5*lg5+lg2*lg50=lg5*lg5+lg2*(lg5+lg10)=lg5*(lg5+lg2)+lg2*lg10=lg5*lg10+lg2*lg10=lg10*(lg2+lg5)=lg10

1.(lg5)2次方+lg2*lg50

1.(lg5)2次方+lg2*lg50(lg5)²+lg2*lg50=(lg5)²+lg2x(lg5*5*2)=(lg5)²+lg2x(lg5+lg5+lg2)=(lg5

:(lg5)的2方+lg2乘lg50

(lg5)^2+lg2*lg50=lg5*lg5+lg2*(lg5+lg10)=lg5*lg5+lg2*(lg5+1)=lg5*lg5+lg2*lg5+lg2=lg5(lg5+lg2)+lg2[这一步

求值 :lg5²+lg2*lg50+(lg2)²

lg5²+lg2*lg50+(lg2)²=2lg5+lg2*lg(5*10)+(lg2)²=2lg5+lg2*(lg5+lg10)+(lg2)²=2lg5+lg

计算:(lg2)的平方+lg2*lg5+lg50!

lg2(lg2+lg5)+lg(5×10)=lg2×1+lg5+lg10=lg2+lg5+1=1+1=2

lg50+lg2*lg5+(lg2)^2=

lg50+lg2*lg5+(lg2)^2=(lg2)^2+lg2lg5+lg(25*2)=(lg2)^2+lg2lg5+2lg5+lg2=lg2(lg+lg5)+2lg5+lg2=lg2*1+2lg5

(lg5)^2 + (lg2)*(lg50)=

(lg5)^2+(lg2)*(lg50)=(lg5)^2+(lg2)*(lg2*25)=(lg5)^2+(lg2)*(lg2+lg5^2)=(lg5)^2+2lg2lg5+(lg2)^2=(lg5+l

(lg5)^2+lg2*lg50 求值

=(lg5)^2+lg2*(lg5+1)=(lg5)^2+(1-lg5)(1+lg5)=(lg5)^2+1-(lg5)^2=1

化简 (lg5)^2+(lg2)lg50

(lg5)^2+(lg2)lg50=(lg5)^2+(lg2)lg5*10=(lg5)^2+(1-lg5)(lg5+1)=(lg5)^2+[1-(lg5)^2]=1

(lg5)²+lg2×lg50

(lg5)²+lg2×(lg5+lg5+lg2)=(lg5)²+2lg2×lg5+(lg2)^2=(lg2+lg5)^2=(lg10)^2=1

lg5²+lg2*lg50化简

lg5²+lg2*lg50化简=lg5²+lg2(lg5×5×2)=lg5²+lg2(2lg5+lg2)=log5²+2×lg2×lg5+(lg2)²

求解(lg5)^2+lg50*lg2

(lg5)^2+lg50*lg2=(lg5)^2+(lg25+lg2)*lg2=(lg5)²+lg5²lg2+(lg2)²=(lg5)²+2lg5lg2+(lg

1 (lg5)^2+lg50*lg2

1.(lg5)^2+lg50*lg2=(lg5)^2+(2lg5+lg2)*lg2=(lg5)^2+2(lg2)(lg5)+(lg2)^2=(lg2+lg5)^2=(lg10)^2=12.log↓b(

(lg5)²+lg2×lg50

(lg5)²+lg2×lg50=(lg5)²+lg2×lg(5×10)=(lg5)²+lg2×(lg5+1)=(lg5)²+lg2×lg5+lg2=lg5×(l

lg2+lg50+lg5怎样计算

原式=lg2*50*5=lg500=2+lg5
