eu gostaria da resoluçao, nao estou consiguindo fazer!
log 16N=-1/2
10^-1/2=16N
16N=1/10^1/2
16N=1/V10
16N=V10/10
4N=(v10/10)/4
4N=V10/40
b)
log(base x)(9/4)=1/2
x^1/2=9/4
(x^1/2)²=(9/4)²
x=81/16
log16 N = -1/2
N = 16^(-1/2)
N = 1/ 16(1/2)
N = 1/ â16
N = 1/4
Logo 4N = 4(1/4)
4N = 4/4
4N = 1
logS 9/4 = 1/2
S^1/2 = 9/4
âS = 9/4
(âS)² = (9/4)²
S = 81/16
