Question

$4 ^{2} \times 5 ^{2}$
​

Answer 1

Answer:

The answer is:-

(- x){}^{2} (- y){}^{2}(−x)2(−y)2 

So, 

If we multiply the same number two times like (- x)(- x) the result will be \bold{x}xbecause (-) and (-) will be cancelled

So,

According to the question,

==> (- 4){}^{2} (- 5){}^{2}(−4)2(−5)2 

==> [(-4)(-4)][(- 5)(-5)[(−4)(−4)][(−5)(−5) 

==> 16 × 2516×25 

==> 400400 

Answer 2

(4²) × (5²)

= (16) × (25)

= 200
