Question

Separate the constants and variables from the following :

`-7,7+"x",7"x"+"yz",sqrt5,sqrt("xy"),(3"yz")/8,4.5"y"-3"x",`

8 −5, 8 − 5x, 8x −5y × p and 3y²z ÷ 4x

Answer 1

Clearly constants are: −7, `sqrt5`, 8 – 5

Variable are: 7 +x, 7x + yz,`sqrt("xy"),(3"yz")/8`,4.5y − 3x,
8 - 5x, 8x − 5y × p and 3y²z ÷ 4x
