Answer:

Susie is 25 years old

Step-by-step explanation:

Let

x = the age Susie has now.

x - 20 = the age she was 20 years ago.

If Susie is 5 times the age she was twenty years ago, then

x = 5 . (x - 20)

x = 5x - 100

4x = 100

x = 25

Susie is 25 years old, which is 5 times the age she was 20 years ago (25 years - 20 years = 5 years).

Answer:

9³

Step-by-step explanation:

We need to find the value of $\dfrac{9^5}{9^2}$ .

We know that,

$\dfrac{x^a}{x^b}=x^{a-b}$

Here, a = 5 and b = 2.

So,

$\dfrac{9^5}{9^2}=9^{5-2}\\\\=9^3$

So, the answer to the given expression is 9³.
