As someone who has stunk at math all his life, you make this so interesting and understandable. Thanks!!!
4. The 2^-2 is the equivalent of 1/4. 1 divided by 1/4 is 4.
Nicely done. Thank you. A refresher
I am a 60 year old math nerd with a High Schooler. Both of us have been watching your videos to keep our math skills sharp. Thanks for doing what you do!
This is “math for dummies” and I appreciate it….🤓🤓
Believe it or not I did very well in math in HS and college. I got very high SAT and ACT scores it’s been over forty years. I’m an idiot now
Yeahhhhh! Your teachings are producing results Mr YT Math. 2 to the negative 2 = 1/2 to the power 2. The rest is easy. :)
Yes! Took about 3 seconds.
So long since I've done any maths but genera arithmetic. You remind and teach well. Thanks.
Thank you
Awesome thanks 👍💪👋😁😎❤️
A) 4
I like maths after 55 years,how easy it was 😌.
Simple: 1 x 2² = 4 so answer A
I understand that we're taught that a negative power flips it to th denominator and vice versa but, that description seems to leave out steps in the process without ever learning the steps that lead to the conclusion when the negative power is in the denominator. 1/x^-y = 1/(1/x^y) = x^y. It seems like I missed a step between the 2nd and 3rd steps but I'm unsure how to write it properly if don't use numbers in place of the variables. 1/2^-2 = 1/(1/4) = 1/.25 = 4. Useful shortcut that we take for granted just like similar to useful formulas we don't usually derive on our own out of convenience or time constraints until maybe much higher maths. Apologies for the paragraph.
An intuitive approach ... Negative powers of positive numbers are not negative numbers. They are, in all cases, positive numbers less than 1. Therefore the the answer must be a positive number greater than 1. The only choice is 4. I'd recommend learning the right way to do this though.
1/(2)^-2=2^2=4
Remembering the rule is great, but if I know how the rule is proven that’s even better. I tutor math and I tell my students over and over again that if you multiply “something” by 1 you haven’t changed its value (the Identity Principal). So, if I multiply 1 / 2^-2 by 1 then I still have the same value. Therefore, if I multiply 1 / 2^-2 by 2^2 / 2^2 I get 2^2 / (2^-2) (2^2). I add the exponents of the divisors since the base is the same and then get 2^2 / 2^0. Any number to the zero power is 1. So, then I have 2^2 / 1 or 2^2 = 4. Note: any number divided by itself is 1, so 2^2 / 2^2 = 1
At the title card, and if I remember correctly, the answer is a) 4.
It is not going to be negative so b and d are ruled out looking at it Answer is 4 I reason that out This problem is Extremely easy I recommend doing problems like this on tests I just wrote the answer down and didn’t show my work …Teachers hate that Lol That was Why I did it They wanted you to show each and every step I would combine steps Funny when I tutor
