Given the expression 12 over 12 to the third power.
4vir4ik [10]
<u><em>Part 1:</em></u>
<u>Before we begin, you need to remember the following rule:</u>
\frac{x^a}{x^b} = x^{a-b}

<u>The given expression is:</u>
\frac{12}{12^3}

Since the base is the same in both numerator and denominator, we can apply the above rule. <u>This means that:</u>
\frac{12}{12^3} = 12¹⁻³ = 12⁻²

<u><em>Part 2:</em></u>
<u>Before we begin, you need to remember the following rule:</u>
x⁻ᵃ = \frac{1}{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 = \frac{1}{(12)^2} =  \frac{1}{12*12} = \frac{1}{144}

Hope this helps :)

What is the value of t in the equation 3(2t + 5) = 5t + 25? (4 points)
SSSSS [86.1K]
3 ( 2t + 5 ) = 5 t + 25

3 * 2 t + 3 * 5 = 5 t + 25

6 t + 15 = 5 t + 25

6t - 5t = 25 - 15

t = 10

Hope this helps!
