QUESTION NO 5 
Solve the statement below to find m value show the working.

a) m=5 
m*=m(3+4)*2 

b) m=2 
m*=((3*4)1/2)-9 

ANSWER NO5

a) m=5 
m*=m(3+4)*2 
m=5*5(7)*2 
m=25*14 
m=350 


b) m=2 
m*=((3*4)1/2)-9 
m=2*(12*1/2)-9 
m=2*6-9 
m=12-9 
m=3 

QUESTION NO 6 

Find the output for the following segment.

a) float var 1=25.12, var 2=15.0; 
if (var 1<=2)cout<<"var1 less or same as var2"; 
else cout<<"var1 bigger than var2"; 

b) in n=20; n/=5; 

ANSWER NO6

a) 
float var 1=25.12, var 2=15.0; 
if (var 1<=2) 
cout<<"var1 less or same as var2"; 
else 
cout<<"var1 bigger than var2"; 

output: 
if(25.12<=2) 
var 1 bigger than var 2
