Answer 1

`12 {y}^(2) - 4 {z}^(3)`

Given :-

`y = 4 \\ z = 3`

Solution:-

`12 {y}^(2) - 4 {z}^(3)`

`12 * {4}^(2) - 4 * {3}^(3)`

`12 * 16 - 4 * 9`

`192 - 36`

`156`

Answer 2

The value of 12y²-4z³ is 156.

Step-by-step Step-by-step explanation:

`{\large{\tt{\underline{\underline{\purple{QUESTION : -}}}}}}`

Find the value of 12y²-4z³ = ?

When y = 4 and z = 3

`{\large{\tt{\underline{\underline{\pink{SOLUTION : - }}}}}}`

`\dashrightarrow{\tt{12{y}^(2) - 4 {z}^(3)}}`

`\dashrightarrow{\tt{12{(4)}^(2) - 4 {(3)}^(3)}}`

`\dashrightarrow{\tt{12{(4 * 4)} - 4 {(3 * 3)}}}`

`\dashrightarrow{\tt{12{(16)} - 4 {(9)}}}`

`\dashrightarrow{\tt{12 * 16- 4 * 9}}`

`\dashrightarrow{\tt{192- 36}}`

`\dashrightarrow{\tt{\underline{\underline{\red{156}}}}}`

Hence, the answer is 156.
