Step-by-step explanation:
<u>Step 1: Define</u>
-8 = 2y - 2
<u>Step 2: Solve for </u><em><u>y</u></em>
- [Addition Property of Equality] Add 2 on both sides: -6 = 2y
- [Division Property of Equality] Divide 2 on both sides: -3 = y
- Rewrite/Rearrange: y = -3
<u>Step 3: Check</u>
<em>Plug in y into the original equation to verify it's a solution.</em>
- Substitute in <em>y</em>: -8 = 2(-3) - 2
- Multiply: -8 = -6 - 2
- Subtract: -8 = -8
Here we see that -8 does indeed equal -8.
∴ y = -3 is the solution to the equation.

Step-by-step explanation:
(16^3/2)^1/2
We know that a^ b^c = a^(b*c)
16 ^(3/2*1/2)
16 ^3/4
Now rewriting 16 as 2^4
2^4^3/4
2 ^ (4*3/4)
2^3
