1) log細粒3(log細粒2大粒2)=
2)log細粒6(3+log細粒3大粒27)=
3)log細粒2大粒16+log細粒3大粒1/9-log細粒5大粒√125=
細粒係log後面個個細粒數...

✔ 最佳答案
1) log細粒3(log細粒2大粒2) = log細粒3(1)
= 0
2)log細粒6(3+log細粒3大粒27)
= log細粒6(3+log細粒3大粒3的立方)
= log細粒6(3+3)
=1
3)log細粒2大粒16 + log細粒3大粒1/9 - log細粒5大粒√125
log細粒2大粒16 =>log細粒2大粒2的4次方 =>4
log細粒3大粒1/9 =>log細粒3大粒3的-2次方 => -2
log細粒5大粒√125 => log細粒5大粒5的1/3次方 => 1/3
所以 = 4*(-2)/(1/3)
= -24
