Mathematics
1 answer:
UkoKoshka [18]2 years ago

Answer:

63

Step-by-step explanation:

If 7 men have 7 wives, that means they have 1 wife each, so that will be 7+7=14. Then each wife has 7 children, so that will be 7×7=49, next we add the children to the men and the wives and get 49+14=63. So the total number of people is 63.

Can some one help me. Solve this equation.
Marina86 [1]

\bold{Given : 2^2^x^-^2 - 2^x^-^1 = 2^x - 2}

\bold{\implies (2^2^x) (2^-^2) - (2^x)(2^-^1) = 2^x - 2}

\bold{\implies \frac{(2^2^x)}{(2^2)} - \frac{(2^x)}{(2^1)} = 2^x - 2}

\bold{\implies \frac{(2^2^x)}{4} - \frac{(2^x)}{2} = 2^x - 2}

\bold{\implies \frac{[2^2^x - (2^x)(2)]}{4} = 2^x - 2}

\bold{\implies [2^2^x - (2^x)(2)] = (4)(2^x) - 8}

\bold{\implies 2^2^x - (2^x)(2) - (4)(2^x) + 8 = 0}

\bold{\implies (2^x)^2 - (2^x)(6) + 8 = 0}

\bold{Let\;us\;take : (2^x) = Z}

\bold{\implies Z^2 - 6Z + 8 = 0}

\bold{\implies Z^2 - 4Z - 2Z + 8 = 0}

\bold{\implies Z(Z - 4) - 2(Z - 4) = 0}

\bold{\implies Z = 4\;\;(or)\;\;Z = 2}

\bold{But : Z = 2^x}

\bold{\implies 2^x = 4\;\; (or) \;\; 2^x = 2}

\bold{\implies 2^x = 2^2\;\; (or) \;\; 2^x = 2^1}

\bold{\implies x = 2\;\;(or)\;\; x = 1}

Anybody, please answer this for me. I'm not good at mathematics
Lostsunrise [7]
Well, its kind of obivious that 2x + 4 stands out, but I think you are asking why. Whereas all other lines shown are vertical or horizontal, 2x+4 is diagonal.
