CAN SOMEONE PLEASE HELPPP!? I NEED HELP IN ALGEBRA, SIMPLIFYING RADICALS! SIMPLIFY THE SQUARE ROOT OF 45a SQUARED!
5 answers
I believe the answer is 3a square root of 5a.
√)45a^2)
=√9 * √5 * √a^2
= 3a√5
=√9 * √5 * √a^2
= 3a√5
answer is actually : 3a square root of 5.
45a^2 simplied is 9a^2 x 5
square root of 9a^2 is 3a.
Square root of 5 is radical 5.
Squaring your answer would check to see if you have the correct answer.
Thus mine is the correct one. Sarah was close.
