Question

How do you simplify `4x ^ { 3} \cdot 5x ^ { 4} \cdot x ^ { 4}`?

Answer 1

Since we are multiplying the same variable `(x)`, we need to multiply the integers and add the exponents.

`4x^3*5x^4*x^4=20x^11`

Explanation:

The `4 and 5` multiply to give us `20`.

The exponents of `x` add up to give us `3+4+4=11`

So, `4x^3*5x^4*x^4=20x^11`
