Question

if 3 power 4 X equal to 81 power minus 1 and 10 power one upon Y equal to 0.0001 find the value of 2 power minus x + 4 y​

Answer 1

Answer:

and you can come over here and there 15+593x+y65,

Answer 2

Answer:

sol,3^4x=[81]^-1and [10]^1upon y =0.0001

3^4x=(81)^-1 and (10)^1 upon y =0.0001

3^4x=(3)^-4

X=-1

and,

(10)^1 upon y=0.0001

(10)^ 1 upon y=(10)^-4

1 upon y=-4

y=1 upon -4

to find the value of 2^-x+4y, we need to substitute the value of x and y

2^-x+4y= 2^1+4(1 upon -4)=2^1-1=2^0=1.
