I think this is right but, 0.000345 = 3.45x10^-4
<u><em>Part 1:</em></u><u>Before we begin, you need to remember the following rule:</u>

<u>The given expression is:</u>

Since the base is the same in both numerator and denominator, we can apply the above rule. <u>This means that:</u>

= 12¹⁻³ = 12⁻²
<u><em>Part 2:</em></u><u>Before we begin, you need to remember the following rule:</u>
x⁻ᵃ =

Now, <u>from part 1</u>, we simplified the expression into 12⁻²
Since the power is negative, we can apply the above rule.
<u>This means that:</u>
12⁻² =

Hope this helps :)
