exercice 151
A= 24/6 * 10⁻³/(10⁵*(10⁻²)⁶
A= 4 * 10⁻³/10⁵*10⁻¹²
A= 4 * 10⁻³/10⁻⁷
A= 4 * 10¹⁰
B= (458,5*9,8)/2 * (10⁻⁵*10⁻³)/10⁵
B=4493,3/2 * 10⁻⁸/10⁵
B=2246,65 * 10⁻¹³
B=2,24665 * 10⁻¹⁰
Exercice 152
volume pavé droit : l*L*h
50*32*210
= 336000 cm³
volume carré : c³
0,002³ = 0,000000008 = 8*10⁻⁸
8*10⁻⁸x = 336000
x= 336000/(8*10⁻⁸)
x= 4200000000000
x= 4,2*10¹²
on pourra mettre 4,2*10¹² cubes de 0,002 m
voila j espere t avoir aider
