Answer 1

`{ \tt{16 {b}^(2) c {}^(12) - 0.25 }}`

» Change the decimal to a fraction:

`= { \tt{ {16b}^(2) {c}^(12) - (1)/(4) }} \\`

» Change the other degrees to indices;

• 16 = 4²
• 4 = 2²

`= { \tt{ \blue{( {4}^(2)) }} {b}^(2) {c}^(12) - \frac{1}{ \red{( {2}^(2) )}} } \\ \\ = { \tt{ {(4bc {}^(6) )}^(2) - (1)/(4) }}`

» Factorize:

`= { \tt{4}^(2) \{ ( {bc}^(6) ) {}^(2) - (1)/(4) \}} \\ \\ { \boxed{ \tt{ = 16 \{ { \blue{{(bc}^(6)) {}^(2) - (1)/(4) } \}}}}}`
