Question

simplify (a^-1÷b^-1)÷ab-1​

Answer 1

Answer:

$\frac{a-ab^{2} }{ab^{2} }$

Step-by-step explanation:

$\frac{a}{b}$ ÷ ab -1

$\frac{a}{b}$ × $\frac{1}{ab}$ -1

$\frac{a}{ab^{2} }$ - 1

$\frac{a-ab^{2} }{ab^{2} }$

Answer 2

Answer:

(1-a) ÷ a²

Step-by-step explanation:

(a^-1 ÷ b^-1 ) ÷ ab - 1

=> { (1/a ÷ 1/b ) ÷ ab} -1

=> ( (b/a) ÷ ab ) -1

=> 1/a² - 1

=> ( 1 - a²) ÷ a²
