To simplify the expression a²a³, we can use the rule of exponents which states that when multiplying two terms with the same base, we can add their exponents together.
In our case, the base is ‘a’. The exponents are 2 and 3. According to the rule:
a² * a³ = a^(2+3)
Now, simply add the exponents:
2 + 3 = 5
This gives us:
a² * a³ = a⁵
So, the simplified form of the expression a²a³ is a⁵.
