Expert Answer
Let x = 3.75
10-12
x1/3 = [3.7510-12] 1/3
Taking logs on both sides , we have
logx1/3 = log [3.7510-12] 1/3
i.e 1/3 log x =1/3 log 3.75 - 12/3 log 10
=1/3 log x =1/3 log 3.75 - 4 (since log 10 = 1)
log x =3[1/3 log 3.75 - 4 ]
log x = log 3.75 -12
x = antilog [ log 3.75 -12]
I assume you can find logs and antilogs and substitute
