Answer:

0.1065

Step-by-step explanation:

Given : $2(3x+1)^5=8$

Solution :

$2(3x+1)^5=8$

$(3x+1)^5=4$

Taking natural log both sides

$ln[(3x+1)^5]=ln 4$

Property : $ln (a^b)=bln(a)$

$5 ln(3x+1)=ln 4$

$ln(3x+1)=\frac{1}{5} ln 4$

$ln(3x+1)=\frac{1}{5} (1.3863)$

$ln(3x+1)=0.27726$

$e^{ln(3x+1)}=e^{0.27726}$

Property : $e^{ln x}=x$

$3x+1=1.3195$

$3x=0.3195$

$x=\frac{0.3195}{3}$

$x=0.1065$

Hence the value of x is 0.1065

How is the pattern for a perfect square trinomial used to factor the trinomial?

anastassius [24]

Answer:

Step-by-step explanation:

We're going to try two things here.

First an example

x^2 + 10x + 25

If you divide the linear factor by 2 and square the result, you get the last number (25)

The pattern of a trinomial is

x^2 + 2b x + b^2

The factors are

(x + b)(x+ b)

Just divide the linear term by 2
