Question

Find the values of the following:
(i) $(-3{)}^2$ (ii) $(-7{)}^2$ (iii) $(-0.3{)}^2$
(iv) ${(-\frac{2}{3})}^2$ (v) ${(-\frac{3}{4})}^2$ (vi) $(-0.6{)}^2$

Answer 1

(i) $(-3{)}^2$

$(-3{)}^2=(-3)\times (-3)=3\times 3=9$

(ii) $(-7{)}^2$

$(-7{)}^2=(-7)\times (-7)=7\times 7=49$

(iii) $(-0.3{)}^2$

$(-0.3{)}^2=(-0.3)\times (-0.3)=(0.3)\times (0.3)=0.09$

(iv) $(-2/3{)}^2$

$(-2/3{)}^2=(-2/3)\times (-2/3)=(2/3)\times (2/3)=4/9$

(v) $(-3/4{)}^2$

$(-3/4{)}^2=(-3/4)\times (-3/4)=(3/4)\times (3/4)=9/16$

(vi) $(-0.6{)}^2$

$(-{0.6}^2)=(-0.6)\times (-0.6)=\left(0.6\right)\times \left(0.6\right)=0.36$
