The algebraic expression 20a⁴b + 15ab³ can be written using a common factor as 5ab (4a³ + 3b²)
<h3>How to rewrite algebraic expressions using a common factor?</h3>
Algebraic expressions are expressions that are made up of variables and constants, along with algebraic operations (addition, subtraction, exponents, etc.
Given: 20a⁴b + 15ab³
The common factor of 20 and 15 = 5
The common factor of a⁴and a = a
The common factor of band b³ is b
Thus, the common factor of 20a⁴b and 15ab³ = 5 × a × b = 5ab
20a⁴b + 15ab³ = 5ab (4a³ + 3b²)
Therefore, 20a⁴b + 15ab³ rewritten using a common factor is 5ab (4a³ + 3b²)
