When something has a negative power you must move it to the denominator to give it a positive power therefore this would then turn into 1/[(5/4)^4] to simplify this (5/4)^4 would be (25/16)(25/16) then finally (625/256) so it would then look like this 1/(625/256) in order to not have a fraction in the denominator you would multiply; 1 x (256/625) which is 256/625.
Answer:
4
Step-by-step explanation:
Answer:
A and D
Step-by-step explanation:
3 - 5x > 2
= -5x > 2-3
= -5x > -1
= x < 1/5
X^3+8
= x^3+2^3
<span>a^3 + b^3 = (a + b)(a^2 – ab + b^2)</span>
so
x^3+8
= x^3+2^3
= (x+2)(x^2-2x+2^2)
= (x+2)(x^2-2x+4)
