Question

please help and check my answers. thank you. log b 5 = 1.1610 log b 2 = .5000 Find each of the following.
(a) log(base b)10
log(base b)5+ log(base b)5= 1.661
(b)log(base b)125
2log(base b)5+log(base b)5
(1.1610)^2+1.1610=2.508921
(c)log(base b)2/5
log(base b)2-log(base b)5
.5000-1.1610=-.661
(d) log(base b)3√25
completely stuck on d
