Przedstaw liczbę w postaci potęgi o podstawie 3:
a) ( 18²×81³)²÷ (4×3 do pot 15)²
powinno wyjść 3²
a) ( 18²×81³)²÷ (4×3 do pot 15)² =
= [(2*9)²*( 3⁴)³]² : ( 2² *3¹⁵)² =
= [ 2²*9²*3¹²]² :( 2⁴*3³⁰) =
= [2²*(3²)²*3¹²]² : ( 2⁴*3³⁰) =
= [ 2²*3¹⁶]² : (2⁴*3³⁰) =
= (2⁴*3³²) : (2⁴*3³⁰) =
= (2⁴ : 2⁴)*(3³²:3³⁰) =
= 2⁰*3² =
= 1*3² =
= 3²
