1+1/x^2 when multiplied by x^2 we get: (x^2+1)/x^2.
The table shows a student's proof of the quotient rule for logarithms.
1 answer:
Answer:
The error is at step (3) .
The correct step (3) will be,
= [by using the laws of indices]
All other steps are correct.
Step-by-step explanation:
The error is at the step (3) , because the student has tried to prove the quotient rule of logarithms by using the property i.e., 'The quotient rule of logarithm' itself , i.e. ,by assuming the property does hold before proving it. So, the proof is fallacious.
The correct step (3) will be,
= [by using the laws of indices]
All other steps are correct.

THE ANSWER IS: 86 degrees
first find the measure of angle a: since all angles of a triangle add up to 180, add the measures of angle b and angle c then subtract it from 180 to get angle a: 62+54=116, 180-116=64
since we know line AD bisects angle a, we can divide 64 degrees by 2 to find angle BAD: which is 32 degrees
then subtract both 62 and 32 from 180 to get 86 degrees for angle ADB
