2⁷⁰×2³⁰×2¹⁴×2¹°=2⁷°⁺³°⁺¹⁴⁺¹°=2¹²⁴

13⁴°:13¹⁵:13¹⁵=3⁴°⁻¹⁵⁻¹⁵=3¹°
13°×13×13¹³×13¹⁴=3°⁺¹⁺¹³⁺¹⁴=3²⁸

96¹⁹⁹⁷:96¹⁹⁹⁶=96¹⁹⁹⁷⁻¹⁹⁹⁶=96¹=96

[tex] 2^{70} * 2^{30} * 2^{14} * 2^{10}= 2^{70+30+14+10}= 2^{124} [/tex]
[tex] 13^{40} : 13^{15} : 13^{15}= 13^{40-15-15}= 13^{10} [/tex]
[tex] 13^{0}*13* 13^{13} * 13^{14}=1* 13*13^{13} * 13^{14}= 13^{1+13+14} = 13^{28} [/tex]
[tex] 96^{1997} : 96^{1996} = 96^{1997-1996} = 96^{1} =96[/tex]
