Answer:
(a^8)/(b^9)
Step-by-step explanation:
Two rules of exponents come into play.
(a^b)/(a^c) = a^(b-c)
a^-b = 1/a^b
__
Applying the first rule, we have ...
(a^3)/(a^-5) × (b^-2)/(b^7) = a^(3 -(-5)) × b^(-2 -7) = a^8 × b^-9
Applying the second rule gives the simplified form ...
= (a^8)/(b^9)
20/100 = 0.20
0.20 * 9 = 1.8
9 - 1.8 = 7.2
The sale price of the DVD is $7.20.
$540
Step-by-step explanation:
$150 × 4 = $600
$600 ÷ 10 = $60
$600 - $60 = $540
