(lg5)的平方+lg2*lg50=多少?(lg5)的平方+lg2*lg50=多少?(lg5)的平方+lg2*lg50=多少?lg5*lg5+lg2*lg50=lg5*lg5+lg2*(lg5+lg1
(lg5)的平方+lg2*lg50=多少?
(lg5)的平方+lg2*lg50=多少?
(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*lg10
=1*1
=1
(lg5)^2+lg2*lg50
=(lg5)^2+lg2*(lg5+lg10)
=(lg5)^2+lg2*lg5+lg2
=lg5(lg5+lg2)+lg2
=lg5+lg2
=1
(lg5)的平方+lg2*lg50
=(lg5)的平方+lg2*(1+lg5)
=(lg5)的平方+lg2*lg5+lg2
=lg5(lg5+lg2)+lg2
=lg5+lg2
=1
(lg5)²+lg2xlg50
=(lg5)²+lg2x(lg25+lg2)
=(lg5)²+lg2x(2lg5+lg2)
=(lg5)²+2lg2lg5+(lg2)²
=(lg5 + lg2)²=(lg10)²=1
lg²5+(1-lg5)(1+lg5)
=lg²5+1-lg²5
=1
(lg5)的平方+lg2*lg50=多少?
(lg5)的平方加上lg2乘以lg50=多少
计算:(lg2)的平方+lg2*lg5+lg50!
(lg)的平方+lg2*lg50= (lg5)的平方+lg2*lg50
(lg5)^2+lg2×lg50=?
(lg5)^2 + (lg2)*(lg50)=
(lg5)^2+lg2*lg50=
(lg5)²+lg2*lg50=?
lg5的平方加lg2乘lg50怎么计算?
Lg5的平方加上lg2乘以lg50怎么算啊?
对数运算:(lg5)的平方+lg2*lg50根号下(lg5的平方-2lg5+1)
lg50+lg2*lg5+(lg2)^2=
lg5乘以lg5的推理过程(lg5)的平方+lg50乘以lg2
(lg5)2+lg2×lg50要过程(lg5)2指LG5的平方
1:求值(lg5)平方+lg2×lg50
lg5的平方+lg2乘以lg50再+(lg2)的平方,怎么算啊
计算:(lg5)2+lg2*lg50=?
(lg5)²+lg2×lg50=?
