计算:9^[log3(2)]-2[1+0.5log2(5)]计算:9^[log3(2)]-2[1+0.5log2(5)]计算:9^[log3(2)]-2[1+0.5log2(5)]9^[log3(2)

计算:9^[log3(2)]-2[1+0.5log2(5)]
计算:9^[log3(2)]-2[1+0.5log2(5)]

计算:9^[log3(2)]-2[1+0.5log2(5)]
9^[log3(2)]-2[1+0.5log2(5)]
=[3^log3(2)]^2-2[log2(2)+log2(5^0.5)]
=2^2-2[log2(2*5^0.5)]
=4-log2[2*5^0.5]^2
=4-log2(20)
