Question

[(4³)² : 4⁴+4² - 2]x[(4³)² : 4⁵+2x4²+4⁷ : 4⁶]

Answer 1

30*40=1200 prima paranteza da 30, iar a doua 40

Answer 2

$(4^{6} : 4^{4}+ 4^{2}-2)*( 4^{6} : 4^{5} + 2* 4^{2} +4)= ( 4^{2}+ 4^{2}-2)*(4+2* 4^{2} +4$)=$(2* 4^{2} -2)*(2* 4^{2}+8)= 2*2* 4^{2}* 4^{2} +2* 4^{2} *8 -2*2* 4^{2} -16= 4^{2}* ( 4^{3}+ 4^{2} - 4-1)=16*75 =1200$
