Question

Simplified form of 3a5-(-a5)

Answer 1

Hey there!

Keep in mind that when you are subtracting a negative term from another term, the negative and subtraction will both cancel out and you'll add the term instead. When you add terms like these, you just add up the coefficients (the numbers in front of the unknown terms) and leave the unknown term the same. Anything that doesn't have a coefficient has an implied 1 in front of it. 

$3a^{5} -(-a^{5})$

$3a^{5} + a^{5}$

$3a^{5} + 1a^{5}$

$4a^{5}$  

$4a^{5}$ will be your answer.

Hope this helped you out! :-)
