Answer:
Cost of bicycle. £403.50
His present savings. £265.90
Amount required. £137.60
Step-by-step explanation:
let y= f(x)= 2/x^2
or, f-1(y) = Root(2/y)
or, f-1(x) = Root (2/x)
this is the inverse function of the given.......
I am not sure what the answer is
let , $a\ge b$
$\therefore a=G\cdot m$ and $b=G\cdot n$
$a-b=Gm-Gn=G(m-n)$
Now, $\gcd(a-b,b)$ clearly is, $G$
