log4 (√(7+4*√3)-√(7-4*√3)=计算过程
log4(1+√2+√3)+log4(1+√2-√3)的值等于
log4(√5-√3)+log4(√5+√3)=?
log4(1+√5-√3)+log4(1+√5+√3)=?
求值:-log2log2√√√2 ,log4 (8)-log1/9 (3)-log√2 (4) ; (log4(3))*(log9(25))*(log5(8))
计算:(log4 3+log8 3)×log9 √2=?
如题{log(2√2) - 3log√3 - 3} / {log9 - log4 + 4}
(log4(3)+log8(3))*(log3(2)+log8(2))-log1/2(^4√32)=?..
各位大神log4(3)log9(2)-log1/2(4√32)怎做啊?是不是?
log4(3a+4b)=log2√ab,求a+b的最小值
log√3^9+log9^27+(1/4)log4^1/16
log√3^9+log9^27+(1/4)log4^1/16
8^log4 7=
(1/4)^log4(3)
计算:(2/3)+log4(7)-log4(28)-9的四分之一次方
求导:f(x) = (5ex^3 + 2π x^2 + 3√2 x + 7)/ log4(16) + log6(36) + log9(81) 求 f'(2)
log7(4)·log4(7)求值①log5(3)·log3(7)·log7(5)②log7(4)·log4(7)
若log4(3a+4b)=log2√ab,则a+b的最小值是( )
