Prove that: (12^13–12^12+12^11)(11^9–11^8+11^7) is divisible by 3, 7, 19, and 37. The answer should be like: x^b*3*7*19*37. Also
n200080 [17]

Answer:

Step-by-step explanation:

Given (12^13–12^12+12^11)(11^9–11^8+11^7),

(12^13–12^12+12^11)(11^9–11^8+11^7) =

[(12^12)12 – 12^12 + 12^11][(11^8)11 – 11^8 + 11^7)

[(12^12)(12 – 1) + 12^11][(11^8)(11 – 1) + 11^7] =

(12^12(11) + 12^11)(11^8(10) + 11^7) =

(12^11(12x11) + 12^11)(11^7(11x10) + 11^7) =

[(12^11)(12x11 + 1)][(11^7)(11x10 + 1)] =

[(12^11)x(11^7)](12x11 + 1)(11x10 + 1) =

[(12^11)x(11^7)](133 x 111) =

[(12^11)x(11^7)](133 x 111) =

[(12^11)x(11^7)](14763) =

[(12^11)x(11^7)](3x7x19x37)

From here, it is clear that the given number is divisible by 3, 7, 19 and 37.

Answer:

5/14

Step-by-step explanation:

P(A or B) = P(A) + P(B) − P(A and B)

25/28 = 23/28 + 12/28 − P(A and B)

P(A and B) = 10/28

P(A and B) = 5/14

BRAINLIEST for the correct answer!
Vladimir [108]

Answer:

answer is A

Step-by-step explanation:

(3x^{2}+5x+1) (x^{2}−2x+4)

=(3x^{2}+5x+1)(x^{2}+−2x+4)

=(3x^{2})(x^{2})+(3x^{2})(−2x)+(3x^{2})(4)+(5x)(x^{2})+(5x)(−2x)+(5x)(4)+(1)(x^{2})+(1)(−2x)+(1)(4)

=3x^{4}−6x^{3}+12x^{2}+5x^{3}−10x^{2}+20x+x^{2}−2x+4

=3x^{4} − x^{3} + 3x^{2} + 18x +4
