Question

Simplify (2a^3) (5a^4)

Answer 1

`(2a^3)(5a^4)`
With this, you multiply the coefficients first, (2)(5)=10
Then when you multiply the variables, you add the exponents,
`(a^3)(a^4)=(a^(^3^+^4^))=a^7`

So you would end up with:
`10a^7`

Answer 2

Answer: 10
`a^(7)`

Step-by-step explanation: Think of this problem of having two parts. The coefficients 2 and 5 and the powers
`a^(4)` and
`a^(7)`. To multiply these two terms together, simply multiply their coefficients and we have to add the exponents because we are multiplying powers.

2 × 5 = 10

`a^(3)` ×
`a^(7)` =
`a^(10)`

Therefore, our answer is 10
`a^(7)`.
