Question

Tính :

                 \(P=\dfrac{\left(81,624:4,8-4,505\right)^2+125.0,75}{\left\{\left[\left(0,44\right)^2:0,88+3,53\right]^2-\left(2,75\right)^2\right\}:0,52}\)

Answer 1

\(P=\dfrac{\left(17,005-4,505\right)^2+93,75}{\left\{\left[\left(0,1936:0,88+3,53\right)^2-7,5625\right]\right\}:0,52}\)

\(=\dfrac{\left(12,5\right)^2+93,75}{\left[\left(0,22+3,53\right)^2-7,5625\right]:0,52}\)

\(=\dfrac{156,25+93.75}{\left[\left(3,75\right)^2-7,5625\right]:0,52}\)

\(=\dfrac{250}{\left(14,0625-7,5625\right):0,52}\)

\(=\dfrac{250}{6,5:0,52}=\dfrac{250}{12,5}=20\)
