a=8 b=3 2⁸ - 2³= 256-8=248
If you look at :42, you have the answer there 9

-1/3
Zdorovo!
🎉🎉
It's a very good question

LHS = 3 x 8^x and RHS = 8 x 111 = 8 x 3 x 37, so 8^x = 8 x 37, so x = 1 + log(37) / log(8) If no calculator, then log(8) = 3 x log(2) and log(37) = log(32 x (1 + 5/32)) = 5 log(2) + log(1 + 5/32) So, log(37)/log(8) = ln(37)/ln(8) = ln(32+5)/(3xln(2)) = 1/3 x [ 5 + ln(1 + 5/32)/ln(2) ] and ln(1+5/32) ~= 5/32 and ln(2) ~= .693 (commonly known value) So, x = 1 + 5/3 + 1/3 x 5/32 x 1/.693 =~ 2.74 (actual value is 1 + ln(37)/ln(8) = 2.736) - so approximate (no calculator) value is good enough to 2 places of decimal 😊🙂😎
RootM=1/2
eyeballed it to 64
just use a calculator
COMO HACES , MUCHOS TE MIRAN Y MUY LEJOS DE UTILIZAR REGLAS MATEMATICAS . ¿ SOS PROFESOR ? ESTE EJERCICIO ES SIMPLE Y NO LLEVA CUADRADO PARA SUPRIMIR .😮😮
Boring
My way is more simple... 8^X * (3) = 888 8^X = 296 By log , 2,47129 / 0,90309 = 2,73648 Bingo ! From Brazil !

Ну это легко 888= 8×100+8×10+8×1

x = -2, 4 seconds, no paper. I'm not polishing my halo, just pointing out how ridiculous these "Math Olympiads" are. Of course, if you want every possible solution ....
actually not only x = 9, but x is also equal to (-9-9√3*i)/2 and (-9+9√3*i)/2 so there are 3 answers
x = 9 is easy
*x√x=9√9 => x=9*
Where did that number 1 on the numerator come from ?
because 2^12-16= 2^-4 and by the rules of exponents 2^-4 can be written as 1\2^4
100*500

You can simplify to 16 - 1/16
Yes
The answer is x = 9
Use log base 2.
If 296 was divisible by 3, I'd agree.
Skibidi toilet
Lol
गलत हैं लऊ*डे 🙄 19.2 आता हैं
