log2(x^2-3)=5 计算
log2(x^2-3)=5 计算
log2(x^2-3)=5
2^5=x^2-3
32=x^2-3
x^2=35
x=±√35
log2(x^2-3)=5
x²-3=2^5
x²=35
x=±√35
log2(x^2-3)=5
x²-3=32
x²=35
x=±√35
log2(x²-3)=5
x² - 3 = 32
x² = 35
x = √35 或 x = -√35
log2(x^2-3)=5 计算
log的计算 :log2(20)-log4(25)= log3(2)×log2(5)×log5(3)=?log2[log2(32)-log2(3÷4)+log2log的计算 :log2(20)-log4(25)= log3(2)×log2(5)×log5(3)=?log2【log2(32)-log2(3÷4)+log2(6)】=?lgx+lg(x+15)=2 ..X
[log2 1]+[log2 2]+[log2 3]+[log2 4]+[log2 5]+...+[log2 1024]=?[x]表示不超过x的最大整数2为底 答案是8204
log2 (x + 3) + log2(x + 2) = 1log2 (x + 3) + log2(x + 2) = 1
计算:(1)log2 (4^3*8^5);(2)log2 3+log2 6-log2 9
log2(x – 2 ) + 2 = log2(5)log2(x – 2 ) + 2 = log2(5)
log2(x – 2 ) + 2 = log2(5)log2(x – 2 ) + 2 = log2(5)
解2log2^(x-5)=log2^(x-1)+1
求解log2(3x)=log2(2x+1)
解方程log2(x+14)-log2(x+6)=3-log2(x+2)
解2log2^(9^x-5)=log2^(3^x-2)+2
log2(x^2+7)-log2(x+5)=3 那个2是底下的那个数
log2(9^x-5)=log2(3^x-2)+2怎么解?用图像可以吗
解-log2^[9^(x-1)-5]=-log2^[3^(x-1)-2]-2
解方程log2(9^x - 5)=log2(3^x - 2)的平方 详细!
解-log2^[9^(x-1)-5]=-log2^[3^(x-1)]-2
|[log2(x)]^2-3log2(x)+1|
解方程:log2(9^x - 5)=log2(3^x - 2)+2解方程log2(9^x - 5)=log2(3^x - 2)+2希望有详细过程.注:log2中的2为log的下标
