MAVERICK [17]

Answer: $f^-^1(x)=\frac{x+5}{11}$

Step-by-step explanation:

To find the inverse, you replace the x with y, and y with x.

$x=11y-5$ [add 5 on both sides]

$x+5=11y$ [divide both sides by 11]

$\frac{x+5}{11} =y$

$f^-^1(x)=\frac{x+5}{11}$

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

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