(2^8 . 5^-5 . 19^0)^-2
using PEMDAS
this = (2^8 * 1/5^5 * 1)^-2
= (5^5 / 2^8)^2
= 5^10 / 2^16
Answer:
4
Step-by-step explanation:
The equation is
x^2 - (2x + 8) = 0 where x is the number to be found.
removing the parentheses by distributing the negative:-
x^2 - 2x - 8 = 0
(x - 4)(x +2) = 0
x = 4, -2.
The value of x must be 4 because it is positive.
Answer:
Step-by-step explanation:
(x - 3)(x + 6)
=x(x + 6) -3(x + 6)
=x*x + x*6 - 3*x - 3*6
=x^2 + 6x - 3x - 18
=x^2 + 3x - 18
2/3 has the greatest Value
