Answer 2

Answer:

Please mark me as brainliest

1) b) 33 ( x+y) because it is an equation in two variable

2) I think there is a problem in question

3) b) 1/4

${2}^{ - 2} = \frac{1}{ {2}^{2} } = \frac{1}{2 \times 2} = \frac{1}{4}$

4)

${2}^{2} + {2}^{3} + {2}^{4} = {2}^{2 + 3 + 4} = {2}^{9}$

5) d) -4/7

$\sqrt[ 3]{ \frac{ - 64}{243} } = \sqrt[3]{ \frac{ - 4 \times - 4 \times - 4}{7 \times 7 \times 7} } \\ = \frac{ - 4}{7}$

6) a) 30

$\sqrt[3]{27000} = \sqrt[3]{30 \times 30 \times 30} \\ = 30$

7) d) 1

8) a) ( a + b ) ( a - b )

9) b) 3

10) d) none

put x = 1

5 × 1 - 3× 1 + 1/2×1

5 - 3 + 1/2

2 + 1/2

(2×2+1)/ 2

5/2
