400+101п+500-51 п при п =43

To find the value of the expression when п = 43, substitute the value of п into the expression:

400 + 101п + 500 - 51п

= 400 + (101 * 43) + 500 - (51 * 43)

= 400 + 4343 + 500 - 2193

= 7343 + 500 - 2193

= 7843 - 2193

= 5650

Therefore, when п = 43, the value of the expression is 5650.
