Sagot :

Bonjour,

a = 2² + 3² = 4 + 9 = 13

donc 13 = 1.3 * 10^1

b = (3 * 10 000)² = 30 000² = 900 000 000 = 9 * 10^8

c = (100 + 0.01) / 100 = 1.0001 = 1.0001 * 10^0

Bonjour,

Mettre sous forme scientifique:

A=√4²+3²

=4+9

=13=1,3×10¹

B=(3×10⁴)²

=(3×1000)²

=30000²

=900 000 000=9×10⁸

C=10²+10-²/10²

=(100+0,01)/100

=1.0001=1.0001×10⁰
