Let's solve this problem step-by-step.
STEP-BY-STEP SOLUTION:
= 1 / 8 + ( - 5 / 12 ) - 3 / 8
= 1 / 8 - 5 / 12 - 3 / 8
= ( 3 - 10 - 9 ) / 24
= - 16 / 24
= - 2 / 3

(v-4t)(v+nt)
=v^2+vnt-4tv-4nt^2
Remember some simle log rules
loga+logb=log(ab)
xloga=loga^x

means

also, if no base is stated, assume base 10
so
log(2x)=-1 is base 10 and translates to
10^-1=2x
1/10=2x
divide both sides by 2 aka times 1/2
1/20=x
3log(2)+log(x)=3
log(2^3)+log(x)=3
log(8)+log(x)=3
log(8x)=3
base 10
10^3=8x
1000=8x
divide both sides by 8
x=125
