Answer 2

Răspuns:

Explicație pas cu pas:

a) (3×2)³:3²= 3³×2³:3²= 3×2³;

b) (5×2)⁴:5³= 5⁴×2⁴:5³= 5×2⁴;

c) (5²×3)²:5⁴,= 5⁴×3²: 5⁴= 1×3²

d) (2×3⁴)³:3¹⁰= 2³×(3⁴)³:3¹⁰= 2³×3²;

e) (5³×2)⁴:5¹²= (5³)⁴×2⁴:5¹²= 1×2⁴;

f) (3×2³)²:2⁴-6²= (3×2³)²:2⁴-(3×2)² = 3²×(2³)²:2⁴-3²×2²=3²×2²- 3²×2²=0;

g) (5×6²)²:6³-12²= 5²×(6²)²:6³-(2×6)²=5²×6-2²×6²= 6(5²-2²×6)= 6(25-24)=6 ;

h) (3²×7³×9)³:(9⁶×7⁸)​= (3²×7³×3²)³:(9⁶×7⁸)= (9²×7³)³:(9⁶×7⁸)=1×1=1
