Question

What is 4-2y (-8y) 6.1?

Answer 1

First, we simplify the expression within the parentheses:

-8y * -8y = 64y^2

Next, we substitute this simplified expression back into the original expression:

4 - 2y(64y^2) + 6.1

Now, we perform the multiplication within the parentheses:

-2y * 64y^2 = -128y^3

Finally, we substitute this result back into the expression:

4 - 128y^3 + 6.1

So, the simplified expression becomes:

-128y^3 + 10.1
