The correct answer would be 10/12, but choose 5/12 since that isn't an option.

Given the expression 12 over 12 to the third power.

4vir4ik [10]

Part 1:
Before we begin, you need to remember the following rule:
$\frac{x^a}{x^b} = x^{a-b}$

The given expression is:
$\frac{12}{12^3}$

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

Part 2:
Before we begin, you need to remember the following rule:
x⁻ᵃ = $\frac{1}{x^a}$

Now, from part 1, we simplified the expression into 12⁻²
Since the power is negative, we can apply the above rule.
This means that:
12⁻² = $\frac{1}{(12)^2} = \frac{1}{12*12} = \frac{1}{144}$

Hope this helps :)

What is the value of x after these statements if the starting value of x is 3.

kolbaska11 [484]

[A]
$3^{2}=9$
$5^{3}=125$
$9\neq25$

Ignore

[B]
$3^{2} = 9$
$9 \ \textgreater \ 3$
Yes

$3^{3}=27$
$4( 3^{2})=36

27 \ \textless \ 36$
Yes

Therefore
$x=3+2=5$

[C]
$4^{5}=1024

 5^{4}=625

1024\ \textless \ 625$
No

$5^{5}=3125

 5^{5}=3125

3125\ \textgreater \ 3125$
No

Ignore

[D]
$5^{5}=3125

 2^{5}=32

3125\ \textgreater \ 32$
Yes

$5^{2}=25
25\ \textless \ 11$
No

Therefore
$x=5+8=13$

[E]
$8\ \textgreater \ 7$
Yes

Therefore
$x = 13^{2}=169$
