Question

The value of expression $(1.4{)}^2\times (0.5{)}^2$ is _____ .

Answer 1

The given expression is $(1.4{)}^2\times (0.5{)}^2$

$(1.4{)}^2\times (0.5{)}^2$

$=(1.4\times 0.5{)}^2[x^2{y}^2=\left(xy{)}^2\right]$

$=(0.7{)}^2$

$=\left(\frac{7}{10}\right)\times \left(\frac{7}{10}\right)$

$=\frac{49}{100}=0.64$
