Answer 3

To simplify the expression $7a^2(5a^4-6)$, we'll distribute $7a^2$ to both terms inside the parentheses:

$7a^2 \times 5a^4 - 7a^2 \times 6$

Now, let's simplify each term separately:

1. $7a^2 \times 5a^4$: When you multiply terms with the same base (in this case, $a$), you add the exponents: $7 \times 5 = 35$, and $2 + 4 = 6$, so $a^6$.

2. $7a^2 \times (-6)$: Multiply the coefficients: $7 \times -6 = -42$, and $a^2$ remains unchanged.

Putting it all together:

$35a^6 - 42a^2$

This is the simplified expression $7a^2(5a^4-6)$.
