Answer:
117
Step-by-step explanation:
Given expression:
[tex]72 \div 8 + 4y^3[/tex]
To evaluate the expression when y = 3, substitute y = 3 into the expression and solve using the order of operations (PEDMAS).
Substitute y = 3 into the expression:
[tex]\implies 72 \div 8 + 4(3)^3[/tex]
Carry out the exponent:
[tex]\implies 72 \div 8 + 4\cdot 27[/tex]
Carry out the division and multiplication:
[tex]\implies 9 + 108[/tex]
Carry out the addition:
[tex]\implies 117[/tex]
