Question

Se considera nr.x=15×10+8×5+10, y=10:2+3²-12:3si z=11²-5×2²-13⁰
a)x-10×y-z,
b)3×x-2×y+5×z
c)x+y+z+10×x×y×z
d)10×x-y×z+x×y​

Answer 1

Explicație pas cu pas:

1)

x=150+40+10

x=200

2)

y=5+9-4

y=10

3)

z=121-20-1

z=100

a)

200-10×10-100= 200-100-100=0

b)

3×200-2×10+5×100=600-20+500=580+500=1080

c)

200+10+10+10×200×10×100=200+6000×1000=

=200+60.000.000=60.000.200

d)

10×200-10×100+200×10=2000-1000+2000=3000

Sper ca nu am gresit nimic!!! :))
