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$a^{7}$.
