Explicație pas cu pas:
1a) [tex](2^{3} )^{1} : 2^{10} +5= 2^{3-10} +5 = 2^{-7} +5 = \frac{1}{2^{7} }+5[/tex]
1b)[tex]3^{3} +3^{2} -(-3)^{2} = 27+9-9=27[/tex]
1c)[tex]2^{29} + 2^{10} / 2^{11} = 2^{29}+0.5[/tex]
1d)[tex]\frac{12^{20} }{2^{10} } = \frac{6^{20}*2^{20} }{2^{10} } = 6^{20} * 2^{10}[/tex]
2)[tex]7^{1}*7^{2}*...*7^{50} = 7^{1+2+...50} =7^{1275}[/tex]
dacă x e exponent atunci x = 1275
altfel x = [tex]7^{1274}[/tex]
