A) \[\frac{1}{5}\]
B) \[\frac{4}{5}\]
C) \[\frac{6}{5}\]
D) \[\frac{2}{5}\]
Correct Answer: C
Solution :
Given\[a\]\[b=a+b\]when\[a>0,\,\,b>0\]. , for other values of\[a\]and\[b\] values of a and b Expression, \[=\frac{\sqrt{{{(8)}^{2}}+{{(-6)}^{2}}}-4}{\sqrt{{{(-3)}^{2}}+{{(-4)}^{2}}}}\] \[=\frac{\sqrt{64+36}-4}{\sqrt{9+16}}\] \[=\frac{\sqrt{100}-4}{\sqrt{25}}=\frac{10-4}{5}=\frac{6}{5}\]You need to login to perform this action.
