log4^25-2log4^10+log2^9×log3^根号5×log5^2
log4^25-2log4^10+log2^9×log3^根号5×log5^2
原式
= lg25/lg4-2lg10/lg4+lg9/lg2×lg√5/lg3×lg2/lg5
= (2lg5)/(2lg2)-2/(2lg2)+(2lg3)/lg2×(½lg5)/lg3×lg2/lg5
= lg5/lg2-1/lg2+1
= (lg5-1+lg2)/lg2
= (lg5+lg2-1)/lg2
= (lg10-1)/lg2
= (1-1)/lg2
= 0
log4
log4^27×log(8)25×log9^5
log4^27×log(8)25×log9^5
log (log2)^2 - (log4)(log20) + (log20)^2

(log2 5+log4 125)log3 2/ log根号3 5
求值:-log2log2√√√2 ,log4 (8)-log1/9 (3)-log√2 (4) ; (log4(3))*（log9(25))*(log5(8))
log4^25等于
log2 20-log4 25
log4^2等于多少?
2^log4(3)
log4(3x-2)
2^log4^3=?
如题{log(2√2) - 3log√3 - 3} / {log9 - log4 + 4}
不等式log4（x^2-3x-4）＞log4（2x+10）的解集是
log4 (x+3)+log(1/4) (x-3)=log(1/4) (x-1)+log4 (2x+1)的解集,
解方程log4 x+1/log4 x=10/3
log4^8+log4^2-(1/4)^0 等于多少?
