1 (lg5)^2+lg50*lg2
2 若A大于1,b大于1,P=log↓b(log↓b A)/log↓b A 则A^p=?

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

1 (lg5)^2+lg50*lg2 (lg5)^2 + (lg2)*(lg50)= (lg5)^2+lg2*lg50 求值化简 (lg5)^2+(lg2)lg50 求解(lg5)^2+lg50*lg2 lg50+lg2*lg5+(lg2)^2= 对数运算：(lg5)的平方+lg2*lg50根号下(lg5的平方-2lg5+1) 1：求值（lg5)平方+lg2×lg50 lg50+lg2*lg5+lg²2=? 计算（lg5)^2+lg2·lg50 (lg5)2+lg2×lg50要过程 1.（lg5）2次方+lg2*lg50
