Solve for x to the nearest hundredth<br> 3^x=38

joja [24]

Answer:

<h2>The value of x is 3.31 to the nearest hundredth</h2>

Step-by-step explanation:

Given the equation $3^{x} = 38$ , to calculate the value of x the following steps must be carried out;

Step 1;

Take the natural logarithm of both sides

$ln3^{x}=ln38\\ xln3 = ln38$

Step 2;

Divide both sides by ln3

$xln3/ln3=ln38/ln3\\x=ln38/ln3\\x=3.31$

The value of x is 3.31 to the nearest hundredth

Answer:

Solution given:

-2x²+7x-6=0

2x²-7x+6=0

Comparing above equation with ax²+bx+c

we get

a=2

b=-7

c=6

By using Vieta's theorem

X1+X2= $\frac{-b}{a}$ = $\frac{7}{2}$

again

X1X2= $\frac{c}{a}$ = $\frac{6}{2}$ =3
