5*4

=

=5*4*2*z*2

40z2

=2root =20

=20+5

Answer 2

Step-by-step explanation:

According to question :

x=2 & z=4

Therefore

Let put the value of "x=2" in 5x^4

5(2)^4

5×2×2×2×2=5×16

5×16=80

Therefore the answer is 80

Now,in 2nd part

put the value of "z=4" in 2z^2

2(4)^2

2×4×4=2×16

2×16=32

Therefore answer is 32
