CAN SOMEONE PLEASE HELPPP!? I NEED HELP IN ALGEBRA, SIMPLIFYING RADICALS! SIMPLIFY THE SQUARE ROOT OF 45a SQUARED!

  • algebra -

    I believe the answer is 3a square root of 5a.

  • algebra -

    √)45a^2)
    =√9 * √5 * √a^2
    = 3a√5

  • algebra -

    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.

    oops, my bad. simple mistake.
