anonymous · Answer

@jim_thompson5910  could you help me with the rest of this one? I have done a few of these for this practice test and thought i did them correctly, but it is telling me my answers are wrong.

anonymous · Answer

when i divide log66/log9 i get 1.9067. Then i should divide that by 2 right? to try and get x alone.

kropot72 · Answer

Basically your working is correct, except I get 1.9068 rounding to 4 decimal places. Yes, divide by 2 to find the value of x.

anonymous · Answer

okay so divided by 2, .953?

When I plug the value x = 0.9534 into the left hand side of the given equation, the result is 66.00086342. How many decimal places are required for the answer?
