4² = 16
Step-by-step explanation:
The applicable rule of exponents is ...
1/a^-b = a^b
So, ...

_____
<em>Additional comment</em>
If you were to evaluate this using the Order of Operations, you would evaluate the exponent first:
1/4^-2 = 1/(1/16)
Then, you would do the division.
1/(1/16) = 16
__
We sometimes find it convenient to manipulate exponential terms to the form with the smallest positive exponents before we begin the evaluation.

Answer:
Step-by-step explanation:
Let age of each twin be x
let age of sister be s
So we can write:
x + 4 = s
The product of the 3 siblings ages is 3482 more than sum. We can write:

This can be simplified as:

We replace s with "x + 4" and solve:

<u>Note:</u> To solve this cubic, we used technology
Thus, we can say the twins are 14 years old
It’s 9. 3x9 is 27. Nothing else times anything equals 27, excluding decimals.
