Umartins1: M2 + n2 = 29 ...... (1) M+n=7....... (2)
From eqn (2), m+n= 7
M= 7-n
Sub for m in eqn (1)
(7-n)2 + n2 = 29
(7-n)(7-n) + n2 = 29
49-7n-7n+n2+n2 = 29
49-14n+2n2 = 29
2n2-14n+49-29= 0
2n2-14n+20= 0
n2-7n+10= 0
n2-5n-2n+10= 0
n(n-5)-2(n-5) = 0
(n-2)(n-5) = 0
n=2 or n=5
When n=2,
Sub for n in eqn (2)
M+n=7
M+2=7
M= 7-2
M= 5
When n=5
Sub for n in eqn (2)
M+n= 7
M+5= 7
M= 7-5
M= 2

Brother firstly i want you to understand that masturbation is a sin. And sin is a spirit greater than a man. You cant stop it on your own except you genuinely give your life to Jesus Christ. The growth of the Word of God in you becomes your empowerment to overcome masturbation. The next thing is for you to do away with objects that leads to it. |

Education › Re: Please Help Me Solve Few Indices Question by parkparky(op): 12:55pm On Dec 01, 2015 |
Drniyi4u: Q1 is kinda odd, they rarely ask to find constants. Nonetheless, to solve for 2 (i.e making 2 d subject), take the log of both sides, log (2^n) = log y n log 2 = log y log 2 = (log y)/n take the natural log of both sides ln (log 2) = ln [(log y)/ n] 2 = ln [(log y)/ n]
Q2. represent 5x by p, then substitute p2 - 15 * p + 50 = 0 p2 - 15p + 50 = 0 solving it quadratically gives 5 and 10 i.e p = 5 and p=10
substitute p by 5x 5x = 5 and 5x = 10 5x = 51 and 5x = 10(taking log of both sides) x =1 and log (5x) = log 10 x = 1 and x log 5 = log 10 x = 1 and x = [(log 10) / (log 5)] i dnt undastnd Q1.. Wat is "ln" |

(1) if 2^n =y. Find 2 (2) 25* - 15 x 5* + 50 =0
N/B 2^n is 2 raise to power n and 25* is 25 raise to power x. Same with 5* |
