Nice Square Root Math Simplification |Find the Value of X

Don’t spend the first thirty seconds rewriting the question.

this guy is writing too much unnecessary step

Left side: combine powers of fractions until you get 5 to the power of 7/8. On the right side, 125^x is the same as 5^3x. 3x = 7/8; x = 7/24. You can also do it by reducing fives until you get 5^(3.5 -12x) = 1, then 3.5-12x = 0, x = 3.5/12, which is the same result

5^7/8 =5^3X 3X=7/8, X=7/24

Agonizingly slow

For the impatient, set the playback speed to 2x.

Why not just use the fractional exponents and get to the answer in half of the steps and less math along the way?

[@frankmccann29]

No wonder kids want to use the calculator on their phone. Does anyone teach how to set up the problem, explaining why actions were done?

[@MuhammadAslam-el6vt]

Sou can simplify the left side as 5 raise to power 7/8 and the right side as 5 raise to power 3x and equate them to get the required answer.

YOU WILL NOT GET ANY MARKS FOR AN ENTRANCE EXAM FOR STEPS FOR CALCULATION

Just square it 3 times.

Finished school 58 years ago. It's fun to review watching though some commenters show shorter ways. Thanks you all.

20 years ago as an engineering student and probably one of the best times of my life, I could just zip through this equations. Thanks for the memorys. NorCal

Bonjour, Je remplace toujours la notation" racine carrée" par "puissance 1/2". C'est toujours plus simple. Merci pour cette démonstration.

[@rameshshankar1010]

Very well explained,had forgotten my maths after 50 yrs

[@antoniolourenco5277]

Excelente .Muito Obrigado . De Portugal

[@nihalepa8174]

Very good presentation 👍

[@KlamKoys766]

Simple explanation that I enjoyed reviewing my past knowledge from 35 yeras ago!

[@Satya.Narayan]

Very beautiful.....

If you do the sqrt2 maths it is easier and faster, you can do it in your head then.
