Simplify : `(1/4)^(-2)+\ (1/2)^(-2)+(1/3)^(-2)`

Explanation

To simplify the expression \((1/4)^{-2} + (1/2)^{-2} + (1/3)^{-2}\), we can follow these steps:

### Step 1: Apply the negative exponent rule
The rule states that \(a^{-n} = \frac{1}{a^n}\) or \(\frac{b}{a^n}\) when expressed as \(\frac{a}{b}\). So, we can rewrite each term:

\[ (1/4)^{-2} = \frac{4}{1^2} = 4^2 \]
