Question

Answer 1

`25^0 +( 1/4)^2 . 4^2`

`= 1 + 1/16 . 16`

`= 1+ 16/16`

`=1 + 1`

`=2`

`----------`

`(-9)/17+((-8)/17)`

`= (-9 +(-8))/17`

`= -17/17`

`=-1`

`-------------`

`-5/2 +(3/4 + 5/2)`

`= -5/2 +(3/4 + 10/4)`

`= -5/2 +13/4`

`=  -10/4 + 13/4`

`=3/4`

Answer 2

d) 25⁰ + (1/4)² . 4²

= 1 + 1/16 . 16

= 1 + 1

= 2

e) (-9/17) + (-8/17)

= -17/17

= -1

f) -5/2 + (3/4 + 5/2)

= -5/2 + 3/4 + 5/2

= 3/4
