Question

me podrían ayudar con el proceso :[
4-² +2²+2-²=​

Answer 1

${4}^{ - 2} + {2}^{2} + {2}^{ - 2}$

$( \frac{1}{4} ) {}^{2} + 4 + {( \frac{1}{2}) }^{2}$

$\frac{ {1}^{2} }{ {4}^{2} } + 4 + \frac{ {1}^{2} }{ {2}^{2} }$

$\frac{1}{16} + 4 + \frac{1}{4}$

$\frac{16 \div 16 \times 1 + 16 \div 1 \times 4 + 16 \div 4 \times 1}{16}$

$\frac{1 \times 1 + 16 \times 4 + 4 \times 1}{16}$

$\frac{1 + 64 + 4}{16}$

$\frac{69}{16}$
