求log2分之根号2 8 log9 根号3 的值

求log2分之根号2 8 log9 根号3 的值 log2^根号下2+log9^27+4^(log4^13) log2 根号2+log9 27+4^log4 13=? log4(3)*log9(2)+log2(4倍根号下64) log9(32)*log64(2log4(3)*log9(2)+log2(4倍根号下64) log9(32)*log64(27)+log9(2)*log4(根27) (log3 4+log3 8)(log2 3+log2 9)+(log3 根号2)(log9 7)/(log1/3 7)(log三次根号4 8) (log3,4+log9,4)log4,3—log2,2根号2 这怎么解答了 3^log9(25)+16^log4(2)-(根号7)^log7(9)+(-1)^log2(1) log9(log2(8)) = x ,求x 8>=x>=根号2 求函数log2（x分之2）乘以log2（4分之x）的最大值和最小值抱歉 题错了 是log2（2分之x）乘以log2（4分之x） log4为底3次方乘以log9为底2次方+log2为底4倍根号下32+16的4分之3次方-2.83分之2次方 (log2（3）+log4（9）+……+log2^n（3^n）)·log9（n次根号8）= 求（log2^3+log8^9)(log3^4+log9^8+log3^2)的值 计算（log2 3+log4 9+log8 27+……+log2^n 3^n）log9 n次根号3计算（log2 3+log4 9+log8 27+……+log2^n 3^n）log9 n次根号32 求函数y=log2分之1根号3x-2 f(X)+log2(X/2)*log根号2（根号X/2),X∈[根号2,8],求F(X)最小值 log2x^2=log2(根号2-1)-log2(根号2+1),求x+1/x 根号2分之[根号32-根号8] 已知log2(x^2)=log2(根号2-1)-log2(根号2+1),求x+1/x
