How do you convert powers to the same base if the bases don't have common factors?

Yuri [45]

Answer:

6²

Step-by-step explanation:

Use the rule of exponents ...

(a·b)^c = a^c·b^c

Your expression has a=3, b=2, c=2.

3²·2² = (3·2)² = 6²

_____

If you want to get more sophisticated than that, logarithms can get involved.

$3^2\cdot 2^2=10^{2\log{(3)}+2\log{(2)}}\approx 10^{1.5563025}$

Y=2x y=7x + 15 substitution

sergejj [24]

$y = 2x \\ y = 7x + 15$

Substitute the given value of y into the equation y=7x+15

$2x = 7x + 15$

Move the variable to the left-hand side and change its sign

$2x - 7x = 15$

Collect like terms

$- 5x = 15$

Divide both sides of the equation by -5

$x = - 3$

Substitute the given value of x into the equation y=2x

$y = 2 \times ( - 3)$

Solve the equation for y

$y = - 6$

The possible solution of the system is the ordered pair (x,y)

$(x,y) = ( - 3, - 6)$
