Question

Write the monomial in standard form:

-8ab(-2.5)b²
(A) 20ab³
(B) 20ab²
(C) -20ab³
(D) -20ab²

Answer 1

To write the given expression in standard form, multiply the coefficients and add the exponents for the same variables.

Step-by-step explanation:

The given expression is -8ab(-2.5)b².

To write it in standard form, we need to simplify the expression by multiplying the coefficients, and adding exponents when multiplying the same variables.

Thus, the expression can be rewritten as -8 × (-2.5) × a × b × b² = 20ab³.
