Question 10.


  • \frac{b {}^( - 4) }{b {}^(9) }


  • \frac{1}{b {}^(9) * b {}^(4) }


  • \frac{1}{ {b}^(13) }

correct option is A

Question 20.


  • \frac{4 {}^(5) (4 {}^( - 8)) }{(4 {}^(3) ) {}^(2) } {}^{}


  • \frac{(4 ){}^(5 - 8) }{ {4}^(6) }


  • 4 {}^( - 3) * 4 {}^( - 6)


  • 4 {}^( - 9)

therefore, D is the correct option
