Question

Use multiplication to expand the expression below. Then compute and/or simplify.
left bracket, minus, b, right bracket, squared
(−b)
2

Answer
Attempt 1 out of 3

Press the dot⋅ button or type the * symbol on your keyboard to represent multiplication. Using times× for multiplication is inappropriate when xx may be used as a variable. For the answer, type the base, then use the a, to the power b a
b
button or type the ^ symbol for an exponent.

Answer 5

(-b)(-b)

Answer 6

To simplify the expression (-2w)(-7w^4), we can multiply the coefficients and combine the variables:

(-2)(-7) = 14

w * w^4 = w^(1+4) = w^5

Therefore, the simplified expression is:

14w^5

Answer 7

To simplify the expression (4c)^2, we square the coefficient and the variable separately:

(4)^2 = 16

c^2 remains unchanged.

Therefore, the simplified expression is:

16c^2

Answer 8

To simplify the expression x^5y^2(2x^2), we can combine the exponents and multiply the coefficients:

x^5 * x^2 = x^(5+2) = x^7

y^2 remains unchanged.

2 * x^2 = 2x^2

Therefore, the simplified expression is:

2x^7y^2

Answer 9

Apologies for the confusion. Let's simplify the expression correctly:

To simplify the expression x^5y^2(2x^2), we can multiply the coefficients and combine the variables:

x^5 * x^2 = x^(5+2) = x^7

y^2 remains unchanged.

2 * x^2 = 2x^2

Therefore, the simplified expression is:

2x^7y^2(2x^2) = 2x^9y^2
