Ummmm. I thought of binomial theorem.
(A+Ab)b=Ab+Cb1A2b−1+Cb2A3b−2+Cb3A4b−3.......
x+3(x−6)=2x−3x+3x−18=2x−34x−18=2x−34x−2x=18−32x=15x=152
2x2×2=2×x2×2=2×2×x2=4×x2=4x2
Same as Guest #1's answer
−65+70=+70−65 Yes, you can exchange the two.=5
Same as ElectricPavlov's answer.
768.500−13.402−−−−−−−−755.098
2×100
limx→27f(x)
That means f(27) usually.
xx2−4+1x+2=3x+1(x−2)=3(x2−4)x+x−2=3x2−123x2−2x−10=0x=−(−2)±√(−2)2−4(3)(−10)2(3)=2±√1246=2±2√316=1±√313∴x=1+√313 OR x=1−√313
(A+A^b)^b
=A(1+A^(b-1))^b
That could not be further simplified.
3^1 mod 5 = 3
3^2 mod 5 = 4
3^3 mod 5 = 2
3^4 mod 5 = 1
3^5 mod 5 = 3
3^6 mod 5 = 4
You see the sequence right?
Because 200 mod 4 = 0. 3^200 mod 5 = 3^0 mod 5 = 1. Guest #2 is correct.
