Question

(-3)² : √9=
2*∛8+3*√4=
⅕*√25-3:∛27=
√¼+(-½)²=
∛1/64+√16*¾ ₂=
√16:√4:(-2)³*(¼)¹=

Answer 1

9/ 3= 3
2* 2+3*2= 4+ 6=10
1/5 *5-3/ 3= 1-1= 0
1/2+1/4= 2/4+1/4= 3/4
1/4+ 4* 9/16= 1/4* 9/4= 9/16
4/2/(-8)* 1/4= -1/4*1/4=-1/16

Answer 2

(-3)² : √9= 9 : 3 = 3

2*∛8+3*√4= 2*2 + 3*2 = 4 + 6 = 10

⅕*√25-3:∛27= ⅕*5 - 3:3 = 1 - 1 = 0

√¼+(-½)²= = ½ + ¼ = ²/₄ + ¼ = ¾

 

W tym przykładzie nie wiem co ta mała 2 na końcu oznacza
∛1/64+√16*¾₂= ¼ + 4*³/₄₂ = ¼ + ²/₇ = ⁷₂₈ + ⁸/₂₈ = ¹⁵/₂₈

albo

∛1/64+√16*(¾)² = ¼ + 4 * ⁹/₁₆ = ¼ + ⁹/₄ = ¹⁰/₄ = 2²/₄ = 2½

albo

∛1/64+√16*³/₄² = ¼ + 4 * ³/₁₆ = ¼ + ¾ = 1

√16:√4:(-2)³*(¼)¹= 4:2:(-8)*(¼) = -¹/₁₆
