Question

[(12)-²]2÷[(12)²]-² = ?​

Answer 1

Answer:

$\frac{ { ({12}^{ - 2}) }^{2} }{ { ({12}^{2}) }^{ - 2} } \\ = \frac{ {(12)}^{ - 2 \times 2} }{ {(12)}^{2 \times - 2} } \\ = \frac{ {12}^{ - 4} }{ {12}^{ - 4} } \\ = {(12)}^{ - 4 + 4} \\ = {12}^{0} \\ \boxed{= \: \underline{ \underline { \bf 1}}}$

Answer 2

Answer:

$\frac{ {(12)}^{2} \times 2 }{ {( {12}^{2}) }^{2} } = \frac{12 \times 12 \times 2}{ {12}^{4} } = \frac{12 \times 12 \times 2}{12 \times 12 \times 12 \times 12} = \frac{2}{12 \times 12} = \frac{2}{144} = \frac{1}{74}$
