12³.2².4⁴ / 4³.2.12²

Nuetrik [128]

Remember
$\frac{xyz}{abc}=( \frac{x}{a} )( \frac{y}{b} )( \frac{z}{c} )$
and
$\frac{x^m}{x^n}=x^{m-n}$

split them to have same bases
$\frac{12^32^24^4}{4^32^112^2}=$
$( \frac{12^3}{12^2} )( \frac{4^4}{4^3} )( \frac{2^2}{2^1} )=$
$(12^1)(4^1)(2^1)=$
$(12)(4)(2)=$
$96$

Question 28 (1 point)

aniked [119]

Answer:

+ 16

Step-by-step explanation:

x² - 8x = - 10

to complete the square

add ( half the coefficient of the x- term )² to both sides

x² + 2(- 4)x + (- 4) = - 10 + (- 4)²

x² - 8x + 16 = - 10 + 16

thus 16 is added to both sides to complete the square

Solve the inequality and enter your solution as an inequality comparing the variable to the solution in the box below. 18 + x &g

storchak [24]

Hi there! :)

Answer:

x>24

*The answer must have a positive sign and greater than symbol sign.*

Step-by-step explanation:

First, you switch sides.

$x+18>42$

Then, you subtract by 18 from both sides of an equation.

$x+18-18>42-18$

Finally, you subtract by the numbers from left to right.

$42-18=24$

Final answer is x>24

I hope this helps you!

Have a nice day! :)
