Question

Find the value of each of the following.
If x = log2(8) and y = 2x, find the value of y.

Answer 1

`6 = y`

Explanation:

`log_a[b] = exponent`

`log_2[8] = x`

This means you have to figure how many times to multiply the base of 2 by, to get 8, and this number would be 3:

`log_2[8] = 3`

Now, plug 3 into the direct variation equation of
`y = 2x`:

`2[3] = y \\ \\ 6 = y`
