Answer:
7.5×10^4
Step-by-step explanation:
Move the decimal so there is one non-zero digit to the left of the decimal point. The number of decimal places you move will be the exponent on the 10. If the decimal is being moved to the right, the exponent will be negative. If the decimal is being moved to the left, the exponent will be positive.

Step-by-step explanation:
Answer:
The error is at step (3) .
The correct step (3) will be,
![\log_{b}(\frac {b^{x}}{b^{y}})](https://tex.z-dn.net/?f=%5Clog_%7Bb%7D%28%5Cfrac%20%7Bb%5E%7Bx%7D%7D%7Bb%5E%7By%7D%7D%29)
=
[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,
![\log_{b}(\frac {b^{x}}{b^{y}})](https://tex.z-dn.net/?f=%5Clog_%7Bb%7D%28%5Cfrac%20%7Bb%5E%7Bx%7D%7D%7Bb%5E%7By%7D%7D%29)
=
[by using the laws of indices]
All other steps are correct.
