When x = 1, then value of |2x – 1| + |x – 3| will be -

If $$ {(x-2)^{2}+(y-{1\over2})^{2}}=0$$, then the value of $$ {x\over y}$$ is

If p = 8.15, q = 9.06 and r = −17.21, then the value of p³+q³+r³-3pqr

$${2}=x+{1\over{1+{1\over5+{1\over{2}}}}}$$ then the value of x is equal to:

If $${32÷16-5×2\over 11÷22×8-5×2}={1\over p}$$then what is the value of P?

Direction : What should come in place of the question (?) in the following question.

$$ {\sqrt{441}}+ {(71)^{2}} -{(?)^{2}}=2707 $$

If  $${{(17)^3-(7)^3}\over (17^2+7^2+k)}=10 $$ , then what is the value of k?
