ingat

a squared equals a cross times a

maka

a. begin mathsize 14px style 20 squared equals space... space cross times space... space equals space... end style

begin mathsize 14px style table attributes columnalign right center left columnspacing 0px end attributes row cell 20 squared end cell equals cell 20 cross times 20 end cell row blank equals 400 end table end style

Jadi, begin mathsize 14px style 20 squared equals 20 cross times 20 equals 400 end style .

b. begin mathsize 14px style 23 squared equals space... space cross times space... space equals space... end style

begin mathsize 14px style table attributes columnalign right center left columnspacing 0px end attributes row cell 23 squared end cell equals cell 23 cross times 23 end cell row blank equals 529 end table end style

Jadi, begin mathsize 14px style 23 squared equals 23 cross times 23 equals 529 end style .

c. begin mathsize 14px style 25 squared equals space... space cross times space... space equals space... end style

begin mathsize 14px style table attributes columnalign right center left columnspacing 0px end attributes row cell 25 squared end cell equals cell 25 cross times 25 end cell row blank equals 625 end table end style

Jadi, begin mathsize 14px style 25 squared equals 25 cross times 25 equals 625 end style .

d. begin mathsize 14px style 28 squared equals space... space cross times space... space equals space... end style

begin mathsize 14px style table attributes columnalign right center left columnspacing 0px end attributes row cell 28 squared end cell equals cell 28 cross times 28 end cell row blank equals 784 end table end style

Jadi, begin mathsize 14px style 28 squared equals 28 cross times 28 equals 784 end style .

e. begin mathsize 14px style 30 squared equals space... space cross times space... space equals space... end style

begin mathsize 14px style table attributes columnalign right center left columnspacing 0px end attributes row cell 30 squared end cell equals cell 30 cross times 30 end cell row blank equals 900 end table end style

Jadi, begin mathsize 14px style 30 squared equals 30 cross times 30 equals 900 end style .
