Answer: 2 log y - log 25

<u>Step-by-step explanation:</u>

Notes: Division expands to subtraction. Exponent expands to multiplication.

$log\bigg(\dfrac{y}{5}\bigg)^2\\\\\\=log\bigg(\dfrac{y^2}{5^2}\bigg)\\\\\\=log(y^2)-log(5^2)\\\\\\=\large\boxed{2log(y)-log(25)}$

Find the value of b that makes <img src="https://tex.z-dn.net/?f=%20x%5E%7B2%7D%20%2Bbx%2B%5Cfrac%7B9%7D%7B4%7D%20" id="TexFormu

Perfect square trinomial is like

(x+4)^2=x^2+8x+16
they are represented as such
ax^2+bx+c
so to solve for b you do
(√c) times 2=b so

c=9/4
square root=3/2 because 3/2 times 3/2=9/4
(√(9/4)) times 2=(3/2) times 2=6/2=3
so b=3

x^2+3x+(9/4)
if factored, it gives
(x+(3/2))(x+(3/2)) or
(x-(3/2))(x-(3/2))

if this equation is equal to 0 then x=-3/2 or 3/2

the value is 3
