Quantity A
\( \dfrac{149!}{148!} = \dfrac{149 * 148!}{148!} = 149\)
Quantity B
\(\dfrac{149!*148!-148!}{147!} = \dfrac{149!*148!}{147!} - \dfrac{148!}{147!} = \dfrac{149!*148*147!}{147!} - \dfrac{148*147!}{147!} = 149!*148 - 148 = 5.637206e+262\)
\( \dfrac{149!}{148!} = \dfrac{149 * 148!}{148!} = 149\)
Quantity B
\(\dfrac{149!*148!-148!}{147!} = \dfrac{149!*148!}{147!} - \dfrac{148!}{147!} = \dfrac{149!*148*147!}{147!} - \dfrac{148*147!}{147!} = 149!*148 - 148 = 5.637206e+262\)
