Answer 2

To evaluate the expression (-2ав)•(3а²в - 5ав²) when a = 1 and b = 1, you simply substitute the values of a and b into the expression and perform the calculations:

Given: a = 1 b = 1

Expression: (-2ав)•(3а²в - 5ав²)

Substitute the values of a and b: (-2 * 1 * 1) • (3 * 1² * 1 - 5 * 1 * 1²)

Simplify: -2 • (3 * 1 - 5 * 1)

-2 • (3 - 5)

-2 • (-2)

Result: 4

So, when a = 1 and b = 1, the expression (-2ав)•(3а²в - 5ав²) evaluates to 4.
