Question

Evaluate the following when X=1, Y= -1 and Z=2


​

Answer 1

Answer:

Step-by-step explanation:

5 X²(8 Y+4 Z²)

X = 1

Y = -1

Z = 2

= 5 (1)²(8*-1+4*2²)

= 5(-8+4*4)

= 5(-8+16)

= 5*8

= 40.

HOPE THIS HELPS.

Answer 2

5(1)^2 * [8(-1)+4(2)^2]

5*(-8+16)

5*8

40 is the ans.. just put the values and rock
