Question

find the value of:
a) x² when x = 5
b) y² when you = -2
c) z² when z = 0.5​

Answer 1

Step-by-step explanation:

a) x² = 5²

x² = 25

b) y² = (-2)²

y² = 4

c) z² = (0.5)²

z² =0.25

Answer 2

Answer:

x= 5

Then, x² = 5²

= 5 ×5

= 25

y = -2

then y² = -2²

= ‐2 ×‐2

= 4

z = 0.5

then, z² = 0.5 ²

= 0.5 × 0.5

= 0.25

x² is 25

y² is 4

z² is 0.25
