much easier way is not this way.

If everyone at the Olympics were as fast as you, the world record for 100 meters would be at 3 h 15 min and 29 sec.

x^4 = 4^4 x^2 = +/- 16 x = +/- 4, +/- 4i

Man, you just do complex 4th root from 4^4 ... that is a one-liner...

SIR SIR SIR SIR HELLO SIT

5^(х-2)=5^2 X-2=2 X=4

Cut the BS. Factor 4^x out without using the fancy 2-1

1) Factor out √5 top and bottom and cancel leaving (√6+1)/(√6-1) 2) Rationalize the denominator

Since the cube of m is bigger than its square when |m| > 1, a real root will be where |m|^3 is a bit less than 150. That suggests |m| = 5. Then m^2 - m^3 = 25 - (-125) = 150, making m = -5. We can now factorise m^3 - m^2 + 150 = 0 because (m + 5) is a factor. So let (m + 5)(m^2 + Am + 30) be the factorisation, then we can see that A = -6 makes the coefficient of m equal to 0. Solve m^2 - 6m + 30 with the quadratic formula x = -(b/2) ± √( (b/2)^2 - ac) = 3 ± √(9 - 30) = 3 ± i√21

brilliant video g

Answering without watching the video Quite a simple question with a little trick to it. Took less tha a min to solve with pure metal calculation Ans: -5

at 1:39 you can't put a bracket with a minus outside without multiplying the terms inside with -1

you fail to prove that 5*(log2/log5)=2

Your solution is wrong the log won't be used separately for the lhs the whole term will be under a single log function

Die Mathematik (bundesdeutsches Hochdeutsch: [matemaˈtiːk], [matemaˈtik]; österreichisches Hochdeutsch: [mateˈmaːtik];[1] von altgriechisch μαθηματικὴ τέχνη mathēmatikē téchnē ‚die Kunst des Lernens‘) ist eine Formalwissenschaft, die aus der Untersuchung von geometrischen Figuren und dem Rechnen mit Zahlen entstand. Für Mathematik gibt es keine allgemein anerkannte Definition; heute wird sie üblicherweise als eine Wissenschaft beschrieben, die durch logische Definitionen selbstgeschaffene abstrakte Strukturen mittels der Logik auf ihre Eigenschaften und Muster untersucht.

Seriously?

Haha, so, now, 1 = 2 Illogical

Germany Math Olympiad Problem: (3ˣ)(3ˣ)(3ˣ) = 21; x =? (3ˣ)(3ˣ)(3ˣ) = 3³ˣ = 21, 3x = log₃21 = log₃3 + log₃7 = 1 + 1.771, x = 2.771/3 = 0.924 The calculation was achieved on a smartphone with a standard calculator app Answer check: x = 0.924, 3x = log₃21: (3ˣ)(3ˣ)(3ˣ) = 3³ˣ = 3^log₃21 = 21; Confirmed Final answer: x = (log₃21)/3 = 0.924

Calculation lengthy and confusing.

Tnx bro😊😊
