Answer 1

a)
4 + 4 x 2 = 4 + 8 = 12
(4 + 4 ) x 2 = 8 x 2 = 16
⇒ $2^{2} + 2^{2} * 2 \ \textless \ ( 2^{2} + 2^{2} ) * 2$

b) 
81 - 81 : 3 = 81 - 27 = 54
( 81 - 81 ) : 3 = 0 : 3 = 0
⇒ $3^{4} - 3^{4} : 3 \ \textgreater \ ( 3^{4} - 3^{4} ) : 3$

c) 
$5^{2}$ = 25
1 + 16 = 17
⇒ $(1+4)^{2} \ \textgreater \ 1^{2} + 4^{2}$

d)
9 x 25 = 225
$15^{2}$ =  225 
⇒ $3^{2} * 5^{2} = (3*5)^{2}$

e)
64 + 64 = 128
$2^{7}$ = 128
⇒ $2^{6} + 2^{6} = 2^{7}$

f)
27 + 27 + 27 = 81
3 x 27 = 81
⇒ $3^{3} + 3^{3} + 3^{3} = 3 * 3^{3}$
