计算:16^(3/4) *(1/2)2 +2lg根号2 +(1/2)lg25 + log 2^9 * log3^4
计算:16^(3/4) *(1/2)2 +2lg根号2 +(1/2)lg25 + log 2^9 * log3^4

计算:16^(3/4) *(1/2)2 +2lg根号2 +(1/2)lg25 + log 2^9 * log3^4
题目应是16^(3/4) *(1/2)^2 +2lg根号2 +(1/2)lg25 + lg 2^9 * lg3^4
=2^3 *(1/4) +lg2 +lg5 + 2lg2 * 4lg3
=8 *(1/4) +1 + 8lg2lg3
=3+ 8lg2*lg3
=3+1.15
=4.15

请问 log 和 lg 一样吗???
