Question

Use the cubic model y=3x^3 to find the value of y when x=8

Answer 1

pemdas

exponent first

y=3(8³)
8³=512
y=3(512)
y=1536

the value is 1536

Answer 2

Answer:

Value of y is 1536.

Step-by-step explanation:

We have given an expression $y=3x^3$

We need to find the value of y when x=8

We will substitute the value of x as 8 in the given expression we get

$y=3(8)^3$

On simplification we get

$y=3(512)$

On further simplification we get:

$y=1536$

Hence, the required value that is the value of y is 1536
