1)Find the other number among these.

a) 5 b) 6.28 c)3.9999 d)-2.3

* Because only d has negative numbers, as opposed to other numbers.

2)Write a rounded figure.

a) 1.65 + 4.47 b) 22.4 + 13.7

=2 +4 = 22+14

=6 = 36

5 or more + 4 or less –

3)Determine each value using a calculator.

a)[3.7-(-1.3)]^3.2

=[3.7+1.3]^3.2

=5^3.2

=16

4)Evaluate.

a) $\frac{3}{4}$ ^ ( – $\frac{2}{9}$ ) Denominator and Numerator division

=- $\frac{1}{6}$

5)Evaluate

a) $\frac{2}{5}$ division $\frac{4}{15}$

Denominator and Numerator exchange

= $\frac{3}{2}$

6)To chooes rational number

a) 17 b)3.141592… c) $\frac{5}{0}$

a =rational number is natural number

7) What is the difference between $4^3$ and 4^3?

$4^3$ = 4^4^4

4^3 = 4+4+4

8) Evaluate

a) $10^3$ ^ $10^4$

=3+4

$10^7$

b) $7^6$ division $7^4$

=6-4

$7^2$

c) $4^3$ division $4^3$

d) ( $10^2)^3$

=2^3

= $10^6$

*BEAMAS

:Brackets

:Exponents

:Divide&Multiply

:Add&Subtract

9)Evaluate.

a) $4^2$ – 8 divition 2 +( $3^2$ )

=16-8 division 2 -9

=16-4-9

b) $4^2$ -8 division 2 +(- $3)^2$

=16 -8 division 2+9

=16-4+9

+21

10)What is the volume &surface area of a cube with an edge Length 4m?

area: l^W. surface area= $4^2$ ^ 6= 96 $m^2$

volume: l^w^h volume = $4^3$ = 64 $m^3$

11) *3n *4n+2 -8m *6+2k

a) Which ones are monomials? 3n

b) Which ones are trinomials? 4n+2-8m

c)Which ones have two terms? 6+2k

12)Simplify

a) 2x +3 +2x -1 b) 4x +2 +x -4x

=2x+2x+3-1 =4x+x-4x+2

=4x+2 =x+2

13)subtract the polynomials.

a) (- $2a^2$ +a -1)- ( $a^2$ -3a +2)

=- $2a^2$ +a -1 – $a^2$ +3a -2

=- $a^2$ +4a -3

*-() = opposites

14)Give the correct answer

a)(4x)^(3x) =7 $x^2$ b) $\frac {20x}{4x}$ =16

=4^3 =20 division 4

=12 $x^2$ =5

15)Expand & simplify

a)-2(x-4) b)5x +2x (3x-5)

=(-2^x)-(2^-4) =(5x^3x)+(5x^-5) +(2x^3x)+(2x-5)

=-2x=8 =15 $x^2$ -25x +6 $x^2$ -10x$

=21 $x^2$ -35x

16)Determine the width of rectangle with Area =10 $x^2$ -15x

and length 5x

=10 $x^2$ -15x) division 5x

=(10 $x^2$ division) – (15x division 5x)

=2x -3

17) Give the correct answer.

$3^0$ =0

X. $3^0$ =1

*zero exponent Law states any base (except 0) raised to an exponent of zero equals ONE

18)Expand

2a(2a-3) -(3a+2b-4)

=2 $a^2$ -6a -3a -2b +4

+2 $a^2$ -9a -2b +4

19)big square+rectangular shape+rectangular shape -small square

= $x^2$ +x+x-1

= $x^2$ =2x-1

20)Rectosahedron l=3a w=2a h=3b surface area

=2(3a^2a + 2a^3b + 3b^3a)

=2(6 $x^2$ =6ab =9ab)

=12 $a^2$ + 12ab =18ab

=12 $a^2$ =30ab

Plus: Add numbers

$3x^2$ + $2x^2$ = $5x^2$

Minus: Subtract numbers

$5x^2$ – $2x^2$ = $3x^2$

Multiplication: Multiply the number by number but the index adds the number of indices in the index.

3x*2x= $6x^2$

Division:Divide out the numbers but the index minus the number of indices in the index.

$4x^2$ division 2x = 2x
