n = -3/2

Step-by-step explanation:

1/4 * sqrt(2) = 2^n

We need to rewrite all the terms so that they are powers of 2

1/4 = 1/2^2 = 2^-2  because if it is in the denominator it is a negative power

sqrt (2) = 2^1/2

Rewriting the left hand side

2^-2 * 2^1/2 = 2^n

When multiplying the same base, we can add the exponents x^a * x^b = x^(a+b)

2^(-2+1/2) = 2^n

Getting a common denominator in the exponent

2^(-4/2+1/2) =  2^n

2^(-3/2) = 2^n

When the bases are the same, the exponents have to be the same

x^(a)  = x^b  means a=b

-3/2 = n

answer: c.  

step-by-step explanation:

mixtures containing substances that get attracted to magnet can be separated using a magnet. we can separate iron from a mixture of sand and iron, as only iron attracts to the magnet.
