|x-4|=|x| x-4=-x x=2 lol the question was easyyy

4^x+4^x=4^2 x+x=2 2x=2 x=1

0,5.

This equation can be rewritten as : (7/5)^(2x)=7/5 so x=1/2.

√x =-1

It is easier and simpler to just factor the polynomial p=m^3+m-130 by using synthetic division, or by observing that the only possible integer solutions of equation p = 0 must be positive integer divisors of 130, that is, no negative solutions are possible, and 1,2,5 are the only prime divisors of 130. Clearly 1 and 2 and not solutions, yet 5 is, and so the polynomial factors as p = (m-5)(m^2+5m+26). Thus, m = 2^x has three possible values as shown, of which two are complex.

Junior olympiad.math problem? Yeah right. More like middleschool math homework problem.

Thanks teacher

Answer is 1.5

2x^2 = 4x x = 2 Why over complicate things?

Why to make it so lengthy? It was to be closed in 3 lines.

Nice

x=log8 base4=3/2

4^x= 8 can be rewritten as 2^2x = 2^3, then it is as easy as 2x=3.

{4x+4x ➖ }=8x^2 2^3x^2 1^1^1x^2 1x^2 (x ➖ 2x+1).

It can be solved in much easier way within 10 sec

X = 3

😮

i loved it thank you

SinxCosx = 0.5 Sin 2x. Differentiate that directly, you get 0.5 x 2 Cos 2x

Well done bro. Please, check the tittle of your video. Is it Rational function OR Fractional function?

Nice

great video, this was very helpful!

😢 can't understand anything

Nice video

well made video bro,keep making videos and stay consistent 💯🙏

Nicely solved.

Good job

It only looks scary 😂 It took me 1 minute and a half once I took a pen and paper. x=½

Bro tell me what is the difference between algebra. Geometric. Logarithms. And matrix

Great job keep it up

Well factorized

Very nicely presented!

Thanks

Y= 6, Y= -2.

Correct

good job

Kbx

Maths is my biggest challenge. I need serious help 😢

Well understood

Good bless my blother! I'm from Brasil😊

Nice
