Question Number 128146 by sahnaz last updated on 04/Jan/21
4<x<5 a=(√(x−3+2(√(x−4))  ))   b=(√(x−4))−1        x−a×b=?
$$\mathrm{4}<\mathrm{x}<\mathrm{5}\:\mathrm{a}=\sqrt{\mathrm{x}−\mathrm{3}+\mathrm{2}\sqrt{\mathrm{x}−\mathrm{4}}\:\:}\:\:\:\mathrm{b}=\sqrt{\mathrm{x}−\mathrm{4}}−\mathrm{1}\:\:\:\:\:\:\:\:\mathrm{x}−\mathrm{a}×\mathrm{b}=? \\ $$

a=(√(x−4))+1  b=(√(x−4))−1  a.b=x−5  x−x+5=5
$${a}=\sqrt{{x}−\mathrm{4}}+\mathrm{1} \\ $$$${b}=\sqrt{{x}−\mathrm{4}}−\mathrm{1} \\ $$$${a}.{b}={x}−\mathrm{5} \\ $$$${x}−{x}+\mathrm{5}=\mathrm{5} \\ $$
