10%5Ex=+1000
log%28%2810%5Ex%29%29=1og%281000%29 Log of both sides.
x=3
My answer is 3.
Correct.
10%5E%282x%2B1%29+=3
log%28%2810%5E%282x%2B1%29%29%29=log%283%29Log both sides.
2x%2B1=+.4771
2x=+-.5229Subtract 1 from both sides and divide by 2.
x=-.2614
My answer is x=.2385
Incorrect.
e%5E%283y%29=1
ln%28e%5E%283y%29%29=ln%281%29Natural log of both sides.
3y=0Divide by 3.
y=0
My answer is x=.7675
Incorrect.
