**Answer:**

4^12 y^24

**Step-by-step explanation:**

(16y^5/4y^3)^12

Simplify inside the parentheses

(16/4 * y^5/y^3) ^ 12

When dividing the bases to the exponent, we keep the base and subtract the exponent

(4 y^(5-3)) ^12

(4 y^2) ^12

Remember (ab)^c = a^c * b^c

4^12 y^2^12

When we have a power to a power, we can multiply the exponents

a^b^c =a^(b*c)

4^12 y^(2*12)

4^12 y^24

**Answer:**

From Least to Greatest: -14.4, -6.8, -23/4, -1.9, 0, 5.4

**Step-by-step explanation:**

**Answer:**

32

**Step-by-step explanation:**

since the question has an even number of age groups, we have to find the two middle numbers which are 30 and 34, add them together and then divide that answer by 2

30 + 34 = 64

64 ÷ 2 = 32

85% liked => 15% didn't like

30 = 15% of x

30 = 0.15 x => x = 30 / 0.15 = 200. This is the total number of students at the library.

Then 200 - 30 = 170 is the number of students whom did like reading mistery stories.

Answer: 170.
