    ✅ Thanks so much for watching! I appreciate you ✌️✌️✌️
    ✅ Just a quick thought on #3, or any exponent for that matter... You can pair off (-3)’s. This is another way to get to the solution. Do (-3) times (-3) = 9 and then the other (-3) times (-3) = 9 as well. You can then do 9 times 9 which equals 81. In other words, you do not have to multiply one (-3) by (-3) at a time. You can pair numbers off as you evaluate an exponent and then multiply the products.
    ✅ Remember, when working with negative bases with parentheses, an EVEN exponent will result in a positive solution. An ODD exponent will result in a negative solution. Something to keep in mind.

    Thank you so much man, honestly, I thought I knew exponents, but my teacher who doesn't know how to teach in our style school system, explained nothing of this. But you? You literally nailed all questions I had in one video. Now that I've watched this, I think I've got it. It's starting to make sense and I'm so glad to have people like you who can explain so *greatly* for people like me

    the pandemic screwed me over, due to feeling trapped my mental health declined and i went back to school late. grades failing i learned nothing during my time at home, i didnt know this would affect everything and now im in 8th grade having to do 8th grade math while looking up videos and teaching myself how to do math from 6th grade to 7th, your videos have helped me learn from the beggining, im taking responsibility and doing it myself as soon when highschool begins i know for certain ill be behind. Thank you very much.

    Basically, if the base is negative and the exponent is even, you'll get a positive answer. If the exponent is odd, you'll get a negative answer? Am I right?

    Why do people get this wrong all the time?
    Look at it this way.
    In this case, it is literally the value of -5 squared, thus positive 25.
    Lots of people, including this video, get this wrong by saying -5 = -1*5, thus -1*5^2 is -25.
    (Even some calculators!)
    However, when you factor a square you must square ALL the factors, thus (-1*5)^2 = -1^2 * 5^2 = 1*25 = positive 25.
    You could also do this using the binomial square formula, (a+b)^2 = a^2 + 2ab + b^2.
    Pick any two numbers that equal -5.
    Lets say positive 10 and negative 15.
    10+(-15) = -5.
    a = 10, b = -15
    10^2 + 2(10)(-15) + (-15)^2
    100+(-300)+225
    -200+225 = positive 25.
    -5^2 is positive 25.
    This will be positive 25 for any two number you choose as long as it equals -5.

    A number with parenthesis and without parenthesis DIFFERENCE:
    Example, we assign x as 5:
    (-5)² = (-5)•(-5) = 25
    Raising a negative base that is inside the parenthesis causing to have the result positive because -(-x) equals x.
    -5² = -25
    Raising a negative base without the parenthesis only affects the number but not the integer so it remains the same integer.
    I hope this helps!

    • @FuckingHostile496

      Imaginary answer. You write -2 as 2 × i^2 but after that I'm also lost.

    • @FuckingHostile496
      @FuckingHostile496 2 года назад +1

      Actually now that I look at it its stupid easy
      (-2)^1.5 = (2*i^2)^1.5 = 2^1.5 * i^(2*1.5) = 2 ^ (3/2) * i^3 = square_root(2^3) * i^2 * i = -2 *square_root(2) * i
      Or you could go like this
      (-2)^1.5= 2^1.5 * (-1)^1.5 = 2*square_root(2) * (-1)*square_root(-1) =2*square_root(2) * (-1)*i = -2i*square_root(2)
      I don't know how i didn't see this in the beginning.
