(-2⅖ )⁻¹:(1¼)⁻²

[4⁻²(1⅕ )⁻³]⁻¹

[2⁻³+(1⅓ )⁻¹]⁻²

no to trzeba rozwiazac ^^



Odpowiedź :

Pozdro
(-2⅖ )⁻¹:(1¼)⁻² = (-12/5)⁻¹ : (5/4)⁻² = - 5/12 : (4/5)² = - 5/12 : 16/25 = -5/12 * 26/16 = -65/96

[4⁻²(1⅕ )⁻³]⁻¹ = (1/16*125/216)⁻¹ = 3456/125 = 26,648

[2⁻³+(1⅓ )⁻¹]⁻² = (1/8 + 6/8)⁻² = (8/7)²= 64/49
⁴/₁₅
27³/₁₂₈
