0,25 - 0,09= berserta caranya SOAL KELAS 5 SD

First, we must expand and simplify : x + y + z = 9
( x + y + z ) 2 = ( 9 ) 2
x 2 + y 2 + z 2 + 2 ( x y + yz + z x ) = 81 **
And Than, Enter the value : **
x 2 + y 2 + z 2 + 2 ( 26 ) = 81
x 2 + y 2 + z 2 + 52 = 81
x 2 + y 2 + z 2 = 81 − 52
x 2 + y 2 + z 2 = 29 ​

we know, (x + y + z)² = x² + y² + z² + 2(xy + yz + xz) 9² = x² + y² + z² + 2 X 26 *** 81 = x² + y² + z² + 52 ***
81 - 52 = x² + y² + z² therefore, x² + y² + z² = 29

The value of x 2 + y 2 + z 2 is 29, which we found using the identity that relates the sums of variables. By squaring the sum of the variables and substituting the given values, we obtained this result. Therefore, x 2 + y 2 + z 2 = 29 .
