Subject: Monomials Explain why (x+y)z is not equal to xz+yz? P.S. Z is an exponent
Education level: Hi, Since the letters x, y and z stand for numbers, you can show that two expressions are not the equal by finding specific numbers x, y and z that give different values for the two expressions. Many choices will work here. For example: ^{z} = (1 + 2)^{2} = 3^{2} = 9
^{z} + y^{z} = 1^{2} + 2^{2} = 1 + 4 = 5
