Thanks 🙏👍 for watching!
Nice technique to solve step by step
Nice solution, please verify.
Verified, please see in comment box.
Verify:
4^x+4^y+4^z=336
4²+4³+4⁴
=16+64+256
=336
Therefore,
X=2,y=3,z=4 is correct answer.
An Important Olympiad Mathematics: 4^x + 4^y + 4^z = 336; x < y < z = ?
4^x + 4^y + 4^z = 336 = (16)(21) = 4²(1 + 4 + 16) = 4² + 4³ + 4⁴
x = 2, y = 3, z = 4
Answer check:
4^x + 4^y + 4^z = 336; Confirmed as shown
Final answer:
x = 2, y = 3, z = 4
336 = 16.21 = 16.(16 + 4 + 1) = (4^2).(4^2 + 4^1 + 4^0)
= 4^4 + 4^3 + 4^2, then a = 4, b = 3, c = 2 (or other order)
Thanks 🙏👍 for your comments
Ec. Are 6 soluții prin permutarea soluției (2 ,3,4 ) PTR.. in enunț nu se specifica nimic despre x, y,z
Thanks for your valuable information.
4 to the power 1 = 4 or 1 he used 1
x=2;y=3;z=4
x=2;y=4;z=3
x=3;y=2;z=4
x=3;y=4;z=2
x=4;y=2;z=3
x=4;y=3;z=2
