Answer:
[tex]5 w^{2}[/tex]
Step-by-step explanation:
Step 1: The given expression is [tex]4 w^{2}+w^{2}[/tex].
Step 2: Let us first know the law of exponents to add two exponents.
The base and the exponents must be the same to add two exponents.
Here base is w and the exponent is 2. They are same.
Step 3: Now add the coefficient of [tex]w^{2}[/tex].
[tex]4 w^{2}+w^{2}=(4+1) w^{2}=5 w^{2}[/tex]
Hence the addition of the expression [tex]4 w^{2}+w^{2} \text { is } 5 w^{2}[/tex].
