Question

if x=16,y=10,z=5 and t=-1,find the value of (x-y)(5√x-y)√(x-y)(z-t).
a)66
b)72
c)76
d)80​

Answer 1

Answer:180(square root 6)

Step-by-step explanation:

Answer 2

x=16

y=10

z=5

t = - 1

Then,

$x-y)(5√x-y)√(x-y)(z-t) \\ = (16 - 10)(5 \sqrt{16 - 10} )( \sqrt{(16 - 10)(5 - - 1) } \\ = 6 \times 5 \sqrt{6} \times \sqrt{6 \times 6} \\ = 30 \sqrt{6 } \times 6 \\ = 180 \sqrt{6}$

Hope this will help...
