Answer:

$\frac{a^2}{b^2}$

Step-by-step explanation:

Apply the exponent rule $a^b*a^c=a^b+c$ to a

$a^4*a^-^2=a^4^-^2=a^2$

$b^3a^2b^-^5$

Apply the exponent rule to b

$b^3*b^-^5=b^3^-^5=b^-^2$

Apply the exponent rule $a^-^b=\frac{1}{a^b}$

$b^-^2=\frac{1}{b^2}=\frac{1}{b^2}a^2=\frac{a^2}{b^2}$

87. Juanita started with 40 dollars in her pocket. Then she bought one CD for 7.99 dollars and 1 DVD for 8.99 dollars. It has a sales tax of 7% on these items. Plus she bought a lunch for 4.25 dollars including tax Solve: => 7.99 dollars + 8.99 dollars = 16.98 dollars => 16.98 dollars * .07 = 1.2 dollars => 16.98 + 1.2 = 18.18 dollars Plus the lunch => 18.18 + 4.25 = 22.43 dollars => 40 – 22.43 = 17.57 dollars
