Answer 1

4.a) $2^{3}$ × $5$ + $3^{2}$ $=$

$8$ × $5$ + $9$

$40$ + $9$ $= 49$

b) $70^{0}$ + $0^{70}$ - $1 =$

$1$ + $0$ - $1$ $=$

$1 - 1= 0$

c) $3$ × $7^{1} - 4$ × $5^{0} =$

$3$ × $7 - 4$ × $1 =$

$21 - 4 = 17$

d) $3^{4} - 2^{4}$ ÷ $8 - 3$ × $4=$

$81 - 16$ ÷ $8 - 3$ × $4 =$

$81 - 2 - 12= \\79 -12 = 67$

e) $5^{2}$ + $3$ × $2 - 4 =$

$25$ + $3$ × $2$ $- 4=$

$25$ + $6 - 4=$

$31- 4 = 27$

f) $5$ × $2^{2}$ + $3-8=$

$5$ × $4$ + $3-8=$

$20$ + $3-8 =$

$23 - 8= 15$

g) $5^{2} - 3$ × $2^{2} - 1 =$

$25 - 3$ × $4 - 1=$

$25-12-1=$

$13-1= 12$

h) $16$ ÷ $2 - 1$ + $7^{2} =$

$16$ ÷ $2 - 1$ + $49=$

$8 - 1$ + $49=$

$7$ + $49=$ $56$
