X^4 - 3x^2 + 2 = 0
(x^2 - 2)(x^2 - 1) = 0
so either x^2 - 2 = 0 or x^2 - 1 = 0
so x^2 = 2 or x^2 = 1
so x = sqrt 2 , - sqrt2, 1 , -1 Answer
all the roots are real
Step-by-step explanation:
5⁵/5⁸
= 5^5-8
= 5^-3
or
(-5)×(-5)×(-5)
= -125
By the law
a^m÷ a^n = a^m-n
Answer:
42× 2= 84 pies
but if u need total, like including what he already had you add 10+84=94 pies
Step-by-step explanation:
so either 84 or 94 in total depending on what your question is asking you
