Make R the subject of the formula.

R = PR +PB/E |

youngest85:can you screenshot ur workings? NB: we have two R in the question |

lytech1: p = [RE/R+b]^2 take square root of both sides ₹p = ₹[RE/R+b]^2 ₹p = RE/R+b cross multiply ₹p(R+b) = RE open bracket and simplify ₹p*R + ₹p*b = RE COLLECT LIKE TERMS ₹p*b = RE - ₹p*R ₹p*b = R(E-₹p) .divide both sides by E-₹p R = ₹p*b/E-₹p........ Note that ₹ stands for square root and * for multiplication sign.....good luck. 3 Likes |

Very wrong NDSMELODY: |

dejt4u:show your workings from the begining till end sir |
Re: Let See Who Can Solve This Simple Mathematics by nolywe(m): 8:08pm On Apr 14, 2020 |
P= RE² ---- (R+b)² P(R+b)²=RE² (PR+Pb)²=RE² PR²+Pb²=RE² PR²+Pb²=E² ------------- R PR+Pb²=E² PR=E² - Pb² R=E² - Pb² ----------- P |

am lost |

NDSMELODY:shown |
Re: Let See Who Can Solve This Simple Mathematics by NDSMELODY(m): 8:16pm On Apr 14, 2020 |
dejt4u:obviously it was a mistake since E only has the square |

lytech1:Lol Has it been solved? |
Re: Let See Who Can Solve This Simple Mathematics by VinceSpence(m): 10:07pm On Apr 14, 2020 |
Op, I think i have been able to answer your question. It's more of a factorization game. Lol R = E^2/P - 2b -b^2 Sorry, I cannot upload the proof. I'm using freebasics. |

Check this out I hope you understand the steps sha Meanwhile, check my signature

This is the soln

Re: Let See Who Can Solve This Simple Mathematics by dejt4u(m): 3:57pm On Apr 15, 2020 |
Akechukwuka:lol.. Wayo wayo.. Why will you let R² be 1 ?? This representation is not valid in mathematics |
Re: Let See Who Can Solve This Simple Mathematics by Akechukwuka: 4:15pm On Apr 15, 2020 |
dejt4u:Are u a mathematician? If yes, I pressasume u 've done laplace transform,,what happen when solving laplace transform eqn.? . There 're some eqn dat need manipulation in order to arrive at wat u 're looking for, but the manipulation must tally with the problem given.. The 1 in quest can be a letter,but I chose 1. |
Re: Let See Who Can Solve This Simple Mathematics by dejt4u(m): 4:38pm On Apr 15, 2020 |
Akechukwuka:lol.. Effect of too much knowledge. You don't need to worry yourself about any manipulation. This is straight forward. You chose to let R² be 1, can you justify why you chose 1. Why don't you choose 2, 3, 4 or any other number.. That your process is not valid at all unless you can justify yourself which I doubt you can |
Re: Let See Who Can Solve This Simple Mathematics by Akechukwuka: 4:52pm On Apr 15, 2020 |
dejt4u: ��..I laff U 're funny, how does dat eqn a striaght one, The 1 in the soln of the eqn above is a constant.. I can decided to use k or any letter, but I chose d numb 1 as constant , Before further prove , and argument with u What level 're u in maths? |
