Solve the following equations.<br> √3 ⋅ 3^3x = 9

GREYUIT [131]

Answer:

The solution is $x = 0.5$

Step-by-step explanation:

We need to write everything as a power of 3.

We know that:

$\sqrt{a} = a^{0.5}$

$\sqrt{3} = 3^{0.5}$

And

$9 = 3^{2}$

This following property is also important:

$\frac{a^{b}}{a^{c}} = a^{b-c}$

To solve, the first step is putting everything with the variable x on one side and everything without the variable x on the other side

$\sqrt{3}.3^{3x} = 9$

$3^{0.5}.3^{3x} = 3^{2}$

$3^{3x} = \frac{3^{2}}{3^{0.5}}$

$3^{3x} = 3^{2-0.5}$

$3^{3x} = 3^{1.5}$

This means that:

$3x = 1.5$

$x = \frac{1.5}{3}$

$x = 0.5$

18 divide by 2 * 3/5-2 simplify show all work

liraira [26]

Answer:

Step-by-step explanation:

I would guess it looks like this - if not then tell me

$\frac{18}{ \frac{2 \times 3}{5 - 2} }$

2×3=6

5-2=3

Then there's only

$\frac{18}{ \frac{6}{3} }$

Which is equal to

$\frac{18}{1} \times \frac{3}{6} = \frac{54}{6} = \frac{9}{1} = 9$
