Question

Tìm x biết: -6-(-1/2)^2+x=(2:1/5)^2

Answer 1

\(-6-\left(-\frac{1}{2}\right)^2+x=\left(2:\frac{1}{5}\right)^2\)

=>\(-6+\frac{1}{4}+x=10^2=100\)

=> \(x=100-\left(6+\frac{1}{4}\right)\)

=> \(x=\frac{375}{4}=93,75\)

Vậy ........

Answer 2

\(-6-\left(-\frac{1}{2}\right)^2+x=\left(2:\frac{1}{5}\right)^2\)

=> \(-6+\frac{1}{4}+x=10^2\)

=> \(-6+\frac{1}{4}+x=100\)

=> x = \(100-\left(6+\frac{1}{4}\right)\)

=> x = \(100-\frac{25}{4}\)

=> x = \(\frac{375}{4}=93,75\)

Vậy x = \(93,75\).
