What is the value of k in the product of powers below?
10^-3 x 10 x 10^k = 10^-3 = 1/10^3
a. -3
b. -1
c. 0
d. 1

B. -1.

Step-by-step explanation:

Note: 10 = 10^1 so:

10^-3 x 10 x 10^k = 10^(-3 + 1 + k) = 10^(k - 2).

So 10^(k - 2) = 10 ^(-3)

and k - 2 = -3

k = 2 - 3 = -1.

step-by-step explanation:

y = 2x

step-by-step explanation:

if you divide each number in the sequence, you'll see that they all have a multiple factor of 2. each number in the series, and any other numbers which may continue, will be multiplied by 2. therefore, y is the next number in the sequence, and x is the current one, so, our formula will be y = 2x.
