WYKONAJ OBLICZENIA:
A. √1⁹/₁₆ × (-2)² + 1,2 × ⁵/₁₂ =
B. 2½ - ½ × ∛3⅜ + 2⁻¹ =
C. (¾)⁻¹ -(-1⅓)² ÷ 0,9 =
D. 0,8 × 3/2³ - (-2)³/4 × 0,1 =
E. (1⅓)² × (-⅓)⁻² - 1,9⁰ × 3⁻¹ =

Proszę o pomoc :) Z góry dziękuję!

Answer 1

A. √1⁹/₁₆ × (-2)² + 1,2 × ⁵/₁₂ =
5/4x4+12/10x5/12=
5+1/2=5i1/2

B. 2½ - ½ × ∛3⅜ + 2⁻¹ =
2i1/2-1/2x3/2+1/2
3-3/4=2i1/4

C. (¾)⁻¹ -(-1⅓)² x 0,9 =
4/3-16/9x9/10=
4/3-16/10=
4/3-8/5=
20/15-24/15=-4/15

D. 0,8 × 3/2³ - (-2)³/4 × 0,1 =
8/10x3/8+8/4x1/10=
3/10+2/10=
5/10=1/2

E. (1⅓)² × (-⅓)⁻² - 1,9⁰ × 3⁻¹ =
16/9x9-1x1/3=
16-1/3=15 i2/3
