Simplify:

left bracket, minus, 4, q, cubed, right bracket, left bracket, 8, q, right bracket
(−4q
3
)(8q)

To simplify the expression, we can multiply the terms inside the parentheses:

(-4q^3)(8q)

To multiply the terms, we multiply the coefficients (-4 and 8) and the variables (q^3 and q):

-4 * 8 = -32
q^3 * q = q^4 (since we add the exponents when multiplying variables with the same base)

Therefore, the simplified expression is:

-32q^4
