Solution:
To solve the expression given in the image, you simply need to combine the like terms. Like terms are terms that have the same variables raised to the same power. Here, both terms are like terms since they both have 'b' as the variable.You simply add the coefficients (the numerical parts) of these like terms:13b + 27b = (13 + 27)b = 40bSo, the expression simplifies to 40b.
