Step-by-step explanation:
[tex]{\large{\tt{\underline{\underline{\purple{QUESTION : -}}}}}}[/tex]
Find the value of 12y²-4z³ = ?
When y = 4 and z = 3
[tex]{\large{\tt{\underline{\underline{\pink{SOLUTION : - }}}}}}[/tex]
[tex] \dashrightarrow{\tt{12{y}^{2} - 4 {z}^{3}}}[/tex]
[tex] \dashrightarrow{\tt{12{(4)}^{2} - 4 {(3)}^{3}}}[/tex]
[tex] \dashrightarrow{\tt{12{(4 \times 4)} - 4 {(3 \times 3)}}}[/tex]
[tex] \dashrightarrow{\tt{12{(16)} - 4 {(9)}}}[/tex]
[tex] \dashrightarrow{\tt{12 \times 16- 4 \times 9}}[/tex]
[tex] \dashrightarrow{\tt{192- 36}}[/tex]
[tex]\dashrightarrow{\tt{\underline{\underline{\red{156}}}}}[/tex]
Hence, the answer is 156.
