How do you work out what 8 cubed is ?
2 answers:
Answer:
512.
Step-by-step explanation:
8 cubed is the same as 8 to the third power.
We usually use other ways to represent certain number to the power to help make equations easier and write less so,
instead of saying: 2 to the second power; we say 2 squared.
Instead of saying 2 to the third power; we say 2 cubed.
The number 2 was used just as example, it could be any number.
so 8 cubed = 8 to the third power so,
8 cubed = = 8x8x8 = 512

<h3>What is an equation?</h3>An equation is an expression that shows the relationship between two or more variables and numbers.
Let x represent the number of individual songs and y represent the number of albums, hence:
x + 8y ≤ 50 (1)
x ≤ 30 (2)
y > 2 (3)
