Question

4¹×4²×...×4⁵⁰ va rog ajutatima va implor si mai am si asta (2²)⁷×2¹⁰÷(2⁴)⁶ si (5⁴)²⁰÷(5²)¹⁰÷5⁵⁰​

Answer 1

Răspuns:

a) 4 la puterea 1+2+......+50

aplicam formula sumei lui Gauss

1+2+...+50

n(n+1)/2

n=50

50(50+1)/2

(50×51)/2

2550/2=1275

4 la puterea 1275

b) 2la puterea14×2la puterea10÷2la puterea24

2la puterea0=1

c) 5la puterea80÷5la puterea20÷5la puterea50

5la puterea10
