All terms are based on the basic laws of logarithms. Learn them.
log3 √3 = 0.5
loga 1 = 0
logm m = 1
0.5 + logx (1/25) + 0 - 1 = -3.5
logx (1/25) = -3
x-3 = 0.04
1 / x3 = 0,04
1 = 0.04x3
25 = x3
3√25 = x

log3√3 = log331/2 = 1/2log33 = 1/2
loga1 = 0 (because a0 = 1)
logmm = 1 (because m1 = m)
So:
log3√3 + logx(1/25) + loga1 - logmm = -3.5
1/2 + logx(1/25) + 0 - 1 = -3.5
logx(1/25) = -3
x-3 = 1/25
1/x3 = 1/25
x3 = 25
x = cuberoot(25)
