Answer:

-3

Step-by-step explanation:

4^x = (1/8)^(x+5)

(2^2)^x =  (2^-3)^(x+5)

2^2x = 2^(-3x - 15)

Since both sides have the same base of 2, then the exponents are equal

So

2x = - 3x - 15

5x = -15

 x = -3

How many times is 5 x 10^6 larger than 5 x 10^4
gayaneshka [121]
<h3>Answer:</h3>

By <em>100 times</em>.

Step-by-step explanation:

Each time something is in Scientific Notation, to every power of 10 something is multiplied by, it grows by 10 times.

By knowing that, if both equations use the same starting number, you can minus the notation section from the larger value, to find the answer.

10^6 - 10^4 = 10^2 ---> 100 times.

Hope that helps, :)
