The simplified form of the expression a2 + a2 + a2 is 3a2. Since the terms are alike, you combine the coefficients to get the final simplified expression.
To simplify the expression a2 + a2 + a2, we just need to add the like terms together.
Since they are all the same term, we can combine them by adding the coefficients.
Each term has a coefficient of 1 (since any number multiplied by 1 is itself), and we have three of these terms.
Adding them together, we get 3a2 as the simplified expression.
Squaring of exponentials involves squaring the digit term in the usual way, and when we have an exponential term, we multiply the exponent by itself.
However, since the exponent here is already 2, we do not need to perform any further squaring.
In conclusion, the simplified form of the given expression is 3a2. This involves basic principles of combining like terms and understanding the concept of exponentials.
