SOMEONE PLS HELP WHAT DO I DO HERE
pav-90 [236]

Answer:

see below

Step-by-step explanation:

4 ^(3x-1)=3

Take the natural log of each side

ln(4 ^(3x-1))= ln (3)

We know that ln ( a^b) = b ln a

(3x-1) ln 4 = ln 3

Divide each side by ln 4

3x-1 = ln(3)/ (ln4)

Add 1 to each side

3x = ln(3)/ ln (4) +1

Divide by 3

x =1/3 [( ln 3)/ ln (4)] + 1/3

x = .792461

PLEEEEEEEAAAAAAASSSSSSSSSSEEEEEEEEEEE help me!!!!!!!!!!

Answer:

\boxed{\sf \ \ \ \dfrac{18}{(x-7)(x+12)(x+30)} \ \ \ }

Step-by-step explanation:

hello,

first of all we will study the quadratic expressions

we can write that, (the different answers provide good clues :-) )

x^2+5x-84=(x-7)(x+12)

and

x^2+23x-210=(x-7)(x+30)

so first of all as we cannot divide by 0 we need to take x different from 7, -12 and -30 and then we can write

\dfrac{1}{x^2+5x-48}-\dfrac{1}{x^2+23x-210}=\dfrac{1}{(x-7)(x+12)}-\dfrac{1}{(x-7)(x+30)}\\\\=\dfrac{(x+30) -(x+12)}{(x-7)(x+12)(x+30)}=\dfrac{x+30-x-12}{(x-7)(x+12)(x+30)}\\\\=\dfrac{18}{(x-7)(x+12)(x+30)}

hope this helps
