Odpowiedź :
a = (2⁻¹)⁴ √16 = 2⁻⁴ × 4 = 2⁻⁴ × 2² = 2⁻² = (½)² = ¼
b = 20
b/a × 100% = 20/(¼) × 100% = 8000%
b = 20
b/a × 100% = 20/(¼) × 100% = 8000%
a = (2⁻¹)⁴ √16 =(½)⁴ razy4= 1/16 razy 4=1/4
1/4 -100%
20 -x
1/4x= 20 razy 100%
x = 2000% razy 4
x=8000%
1/4 -100%
20 -x
1/4x= 20 razy 100%
x = 2000% razy 4
x=8000%
