Question

II) Find the squares of:
(i) -3/7
(ii) -9/17
III) Find the cubes of the following:
(a) 0.3
(b) 0.8​

Answer 1

Answer:

Find the squares of:

-3/7

= -3²/7²

= 9/49

-9/17

= -9²/17²

= 81/289

Find the cubes of the following :

a) 0.3

= 0.3×0.3×0.3

= 0.027

b) 0.8

= 0.8×0.8×0.8

= 0.512

Answer 2

Step-by-step explanation:

Squares :-

${ (\frac{ - 3}{7}) }^{2} \: = \: \frac{9}{49}$

${ (\frac{ - 9}{17} )}^{2} \: = \: \frac{81}{289}$

Cubes :-

(0.3)³ = 0.027

(0.8)³ = 0.512
