Given log b 3 = 0.8397 and log b 7 = 1.4873. Find log b 3b Is the right answer 0.8397

My choices for this question are a x = log8 over log 3 b x log = log 8 c x=log 3 over log 8 d x= ln8 over ln3

Can you please tell me me if the expression or equation that is equivant to 8^x=3 would be x log 3 = log 8?

Rewrite the following as an equivalent logarithmic equation.Do not solve. y^t = x answer logy+logt=logx-is this right also Express as an equivalent expression that is a sum of logt (3ab) the t is at the bottom of the g answer log3+loga+logb logarithms.

Is this right
I need to express as an equivalent expression that is a sum of logarithms. logt 13ab2 is this right (log+13t+loga+log+b+log+2)

Is this algebra question right
Do you rewrite the following as an equivalent logarithmic equation yt=x as E^2-2=7.3891?

Algebra
what would be the approximation to the nearest ten-thousandth log 8900 over log 110?

Not sure where to go next. I need to solve this quadratic equation 7x^2-5=0. This is what I have so far, not sure where/what to do next x=2/7 x=sqrt2/7 or x=-sqrt2/7* =+/-sqrt2/7 +/-sqrt14/7 not even sure if this is right.

algebra-Am I right so far
Use the quadratic formula to determine the x-intercepts (if any)f(x)=2x^2=2 am I right so far? f(x)ax^2+bx+c y=ax^2+bx+c y=2x^2+2 y=0=>2x^2+2=0 =>2x^2+2=0 ax^2=2,bx=2,c=0 x=b=sqrtb^2+4ac over 2a x=(2)+sqrt(2)^24(2)(0)over2(2) x=sqrt4+4over 2
