Question

How to solve 2a x a x a x3a + b +4b

Answer 1

$2a \cdot a \cdot a \cdot 3a +b+4b\\\\=6a^{1+1+1+1} +5b\\\\=6a^4 +5b$

Answer 2

Answer:

$6 {a}^{4} + 5b$

Step-by-step explanation:

$2a \times a\times a \times 3 a+ b + 4b \\ 2a \times a = 2 {a}^{2} \\ 2 {a}^{2} \times a = 2 {a}^{3} \\ 2 {a}^{3} \times 3a = 6 {a}^{4} \\b + 4b = 5b$

Therefore the answer is

$6 {a}^{4} + 5b$
