The second is correct.
The third is correct. Remember xlny=ln(y^x).
The number four is not correct. Only is equal to the first two terms.
The number five is not correct. Is the same that number four.
Good luck!
Answer:
let the larger number be x and smaller number be y
1 equation
x-y=19
or x=19+y
2 equation
x=4y-8
then
putting valu of x in eqn 2nd
19+y=4y-8
19+8=4y-y
27=3y
y=9
so putting value of y in eqn 1
x= 19+9
x=28
therfore, larger number =28
smaller number =9

Answer:
(x+25)(x-30)
Step-by-step explanation:
Express 45 = 40+5 then
8 times 45 can be written
8(40+5) = 320+40 = 360
