Question

Answer 1

`a)3. 5^2+15 . 2^2 - 26:2`

`=3 .25 + 15.4 - 26:2`

`=75 + 60 - 13`

`= 135-13`

 `=122`

`b) 5^3 . 2 -100 : 4 + 2^3 .5`

`= 125.2 - 25 + 8.5`

`= 250 - 25 + 40`

`= 225+40`

`=265`

`c) 6^2 : 9 + 50.2 -3^3 .3`

`=36  : 9 +100-27 .3`

`=4 + 100-81`

`=104 - 81`

`=23`

`d)3^2 .5 + 2^3 .10 - 81 :3`

`=9 .5 + 8 .10 - 27`

`=45 + 80-27`

`= 125-27`

`= 98`

 

Answer 2

\(a,3.5^2+15.2^2-26:2=3.25+15.4-26:2=75+60-13=135-13=123\)

\(b,5^3.2-100:4+2^3.5=125.2-25+8.5=250-25+40=225+40=265\)

\(c,6^2:9+50.2-3^3.3=36:9+100-27.3=4+100-81=104-81=23\)

\(d,3^2.5+2^3.10-81:3=9.5+8.10-27=45+80-27=125-27=98\)
