الاختبار القبلي

استعمل ترتيب العمليات لتحسب ذهنياً:

$\begin{aligned} 14 + 15 \end{aligned}$

$10 + 15 = 15 + 14 = 29$

$\begin{aligned} 6 \times 12 \end{aligned}$

$16 \times 12 = 12 \times 6 = 72$

$\begin{aligned} (25 + 35) \div 9 \end{aligned}$

$(25 + 35) \div 9 = 60 \div 9 = 6.666$

$\begin{aligned} 8^{2} \end{aligned}$

$8^{2} = 8 \times 8 = 64$

$\begin{aligned} (10)^{2} \end{aligned}$

$10^{2} = 10 \times 10 = 100$

$(15)^{2}$

$15^{2} = 15 \times 15 = 225$

استعمل ترتيب العمليات وجد الناتج لكل مما يأتي:

$\begin{aligned} (6 - 7) \times (10 + 4)^{2} - 20 \end{aligned}$

$\begin{aligned} (- 1) \times (14)^{2} - 20 \\ = - 1 \times 196 - 20 \\ = - 196 - 20 = - 216 \end{aligned}$

$\begin{aligned} 100 \div 4 + 2 \times (- 2) \end{aligned}$

$\begin{aligned} 25 + (- 4) \\ = 25 + (- 4) = 21 \end{aligned}$

$\begin{aligned} 50 \div 5 + 4 \times (- 4) \end{aligned}$

$10 + (- 16) = - (16 - 10) = - 6$

$\begin{aligned} 5 - 6 \times 10^{2} + 4 - 2 \times (- 4) \end{aligned}$

$\begin{aligned} 5 - 6 \times 100 + 4 - (- 8) \\ = 5 - 600 + 4 + 8 \\ = (5 + 8 + 4 - 600) \\ = 17 - 600 = - 583 \end{aligned}$

$\begin{aligned} (56 \div 7)^{2} + (60 \div 3) \end{aligned}$

$8^{2} + 20 = 64 + 20 = 84$

$\begin{aligned} (6 \times 20) + 2 (- 4) \div 6 \end{aligned}$

$\begin{aligned} 120 + (- 12 \div 6) \\ = 120 + (- 2) = 118 \end{aligned}$

جد قيمة العبارات الجبرية الآتية:

$\begin{array}{lll} 4 X - 6^{2} & , & X = 3 \end{array}$

$\begin{aligned} 4 X - 6^{2} = 4 \times 3 - 6^{2} \\ = 12 - 36 = - 24 \end{aligned}$

$\begin{array}{lll} 2 X + 8 & , & X = 4 \end{array}$

$\begin{aligned} 2 X + 8 & = 2 (4) + 8 \\ = 8 + 8 = 16 \end{aligned}$

$\begin{array}{lll} 7 (x - 3) & , & X = - 1 \end{array}$

$\begin{aligned} 7 (X - 3) = 7 (- 1 - 3) \\ = 7 \times (- 4) = - 28 \end{aligned}$

$\begin{array}{lll} \sqrt{36} y - 4 & , & y = 2 \end{array}$

$\begin{aligned} \sqrt{36} y - 4 = \sqrt{36} \times 2 - 4 \\ = 6 \times 2 - 4 = 12 - 4 = 8 \end{aligned}$

$\begin{array}{lll} | - 9 | + y^{2} - 25 & , & y = - 5 \end{array}$

$\begin{aligned} | - 9 | + y^{2} - 25 \\ = | - 9 | + (- 5)^{2} - 25 \\ = 9 + (25) - 25 = 9 \end{aligned}$

$\begin{array}{lll} 3 Z + 4 & , & Z = - 1 \end{array}$

$\begin{aligned} 3 Z + 4 = 3 (- 1) + 4 \\ = - 3 + 4 = 1 \end{aligned}$

حل معادلات الجمع والطرح لكل مما يأتي:

$\begin{aligned} X - 9 = 8 \end{aligned}$

$x = 8 + 19 \Rightarrow x = 27$

$\begin{aligned} Z - 4 = 8 \end{aligned}$

$z = 8 + 4 \Rightarrow z = 12$

$\begin{aligned} h + 3 = 12 \end{aligned}$

$H = 12 - 3 \Rightarrow H = 9$

$\begin{aligned} 27 - Z = 24 \end{aligned}$

$\begin{aligned} 27 - 24 = z \\ z = 27 - 24 \Rightarrow z = 3 \end{aligned}$

$\begin{aligned} y + 3 = 9 \end{aligned}$

$y = 9 - 3 \Rightarrow y = 6$

$\begin{aligned} v - 5 = 10 \end{aligned}$

$v = 10 - 5 \Rightarrow v = 15$

$\begin{aligned} y + 11 = 11 \end{aligned}$

$y = 11 - 11 \Rightarrow y = 0$

$\begin{aligned} X + | - 10 | = 5 \end{aligned}$

$\begin{array}{r} x + 10 = 5 \Rightarrow x = 5 - 10 \\ x = - 5 \end{array}$

$\begin{aligned} X \times \frac{1}{2} = 2 \end{aligned}$

$x \div \frac{1}{2} \Rightarrow x = 2 \times \frac{2}{1} \Rightarrow x = 4$

$\begin{aligned} X \times \frac{1}{12} = 6 \end{aligned}$

$x = 6 \div \frac{1}{12} \Rightarrow x = 6 \times \frac{12}{1} \Rightarrow x = 72$

$\begin{aligned} 71 \times y = 213 \end{aligned}$

$y = 213 \div 71 \Rightarrow y = 3$

$\begin{aligned} 8 \times y = 64 \end{aligned}$

$y = 64 \div 8 \Rightarrow y = 8$

$\begin{aligned} 7 \times k = 42 \end{aligned}$

$K = 42 \div 7 \Rightarrow K = 6$

جد قيمة الجذر التربيعي والجذر التكعيبي لكل مما يأتي:

$\sqrt{64}$

$\begin{aligned} \sqrt{64} = \sqrt{2^{6}} = 2^{3} = 8 \end{aligned}$

$\sqrt{100}$

$\sqrt{100} = \sqrt{10^{2}} = 10$

$\sqrt{81}$

$\begin{aligned} \sqrt{81} = \sqrt{3^{4}} = 3^{2} = 9 \end{aligned}$

$\sqrt{144}$

$\begin{array}{r} \sqrt{144} = \sqrt{2^{4} \times 3^{2}} \\ = 2^{2} \times 3 = 12 \end{array}$

$\sqrt{900}$

$\begin{array}{r} \sqrt{900} = \sqrt{3^{2} \times 2^{2} \times 5^{2}} \\ = 3 \times 2 \times 5 = 30 \end{array}$

$\sqrt{625}$

$\begin{aligned} \sqrt{625} = \sqrt{5^{4}} = 5^{2} = 25 \end{aligned}$

$\sqrt[3]{- 125}$
