Evaluate 5+3^x for (a) x=-2 and (b) x=3 . Write your answers in simplest form.

a: 3 to the power of -2 is 1/9 = 5 1/9

b: 3 to the power of 3 = 27

5+27 = 32

Step-by-step explanation:

x = 10

Step-by-step explanation:

First you need to add like terms (x + x), which would give you 2x.

2x + 2 = 22

Then subtract 2 from both sides, causing it to cancel out one side, and 22 - 2, on the other side:

2x + 2 = 22

      -2     -2

22 - 2 is 20, giving you:

2x = 20

Then divide both sides by 2:

2x/2 = 20/2

And you should get x = 10 as your answer.
