Answer 2

1. To simplify the expression -7a¹b7 6a³b4, we can multiply the coefficients and combine the variables with the same base.

-7a¹b7 6a³b4 can be rewritten as:

-7 * 6 * a¹ * a³ * b7 * b4

Multiplying the coefficients gives us:

-42

For the variables with the same base (a and b), we can add their exponents:

a¹ * a³ = a¹+³ = a⁴

b7 * b4 = b7+4 = b¹¹

Putting it all together, the simplified expression is:

-42a⁴b¹¹

2. To simplify the expression (-5x6y³)², we need to square each term inside the parentheses.

(-5x6y³)² can be expanded as:

(-5)² * (x6)² * (y³)²

Squaring each term gives us:

25 * x² * 36 * y⁶

Multiplying the coefficients, we have:

25 * 36 = 900

The simplified expression is:

900x²y⁶
