Log5 35+2log1/2√2-log5 1/50-log5 14
=log5 (5×7)+2log2^(-1) 2(1/2)-log5 (25×2)^(-1)-log5 (2×7)
=(1+log5 7)+2×(-1/2)+(2+log5 2)-(log5 2+log5 7)
=2

Log5^35+2log1/2^√2-log5^1/50-log5^14求值
1、计算log5^35+2log1/2^根号2-log5^1/50-log5^14 2、已知log3^7=a,log2^3=b,求log21^28
对数 log5(35)+2log1/2( 根号2)-log5(1/50)-log5(14)log5(35)+2log1/2( 根号2)-log5(1/50)-log5(14)
计算2log5^10+log5^0.25=
2log5 10+log5 0.25 怎样计算,
计算(2lg5^2+log5^3)/(log5^10+0.5log5^0.36+1/3log5^8)
怎样计算(log2)^2+(log5)^2+(2*log2)*log5
计算:2log5 10+log5 0.25=______
计算:log5为底35的对数-2log5为底3分之7的对数+log5为底7的对数-log5为底1.8的对数
log5【35】-2log5[7/3】+log5【7】-log5【1.8】 化简
log5(35)-2log5(7/3)+log5(7)-log5(1.8)
计算:2log5 10+log5 0.25+5log5 25 (都是以5为底的.)
高一数学,log5^3=a,log5^2=b,用a、b表示,log1.5^2.4
log2(2)+log5(1)-log1/3(1/27)+[3^log3(5)]^2+3^-log3(2)=?
不等式log5(4+3x-X^2)> log1/5(2x+10)的解集是xiexie
已知log2[log1/2(log2x)]=log3[log1/3(log3y)]=log5[log1/5(log5z)]=0.求x2+y^3-z^5的值
一道高一数学题对数log2,详见补充已知log2[log1/2(log2^x)]=log3[log1/3(log3^y)]=log5[log1/5(log5^z)]=0,试比较x,y,z的大小?
