Answer 1

×Răspuns:

a=3⁷×5¹⁶×7³

b=4¹⁰×3⁸×7¹⁴

N=a×b

N=3⁷×5¹⁶×7³×4¹⁰×3⁸×7¹⁴= 3⁷⁺⁸×5¹⁶×7³⁺¹⁴×4¹⁰= 3¹⁵×7¹⁷×5¹⁰×5⁶×4¹⁰= 3¹⁵×7¹⁷×5⁶×(5×4)¹⁰= 3¹⁵×7¹⁷×5⁶×20¹⁰= 3¹⁵×7¹⁷×5⁶×2¹⁰×10¹⁰= 3¹⁵×7¹⁷×5⁶×2⁴×2⁶×10¹⁰= 3¹⁵×7¹⁷×(5×2)⁶×2⁴×10¹⁰= 3¹⁵×7¹⁷×10⁶×2⁴×10¹⁰= 3¹⁵×7¹⁷×2⁴×10¹⁶= 3¹⁵×7¹⁵×7²×2²×2²×10¹⁶= (3×7)¹⁵×(7×2×2)²×10¹⁶= 21¹⁵×28²×10¹⁶
