If a^2=b^2, does a=b? explain and justify your answer.

  not necessarily

Step-by-step explanation:

Taking the square root of both sides, you have ...

  ±a = ±b

Those four cases resolve to two unique cases:

  a = ±b

The given equation will be true if a = b or if a = -b. If a and b are constrained to have the same sign, then a=b is the only solution.

hi

step-by-step explanation:

i think this could be a possible answer (1 / 84) -1

good luck! : d
