Answer:
2) 
3) 5√2
Step-by-step explanation:
Simplest radical form of an expression is the expression in radical so that there are no more square roots, cube roots, 4th roots, etc left to find, after rationalising the denominator ( if needed ).
2. Here the given expressions,

For rationalising the denominator multiply both numerator and denominator by √11,

3. given expression,




If you would like to write x^4y - 4x^2y - 5y in a completely factored form, you can do this using the following steps:
x^4y - 4x^2y - 5y = y * (x^4 - 4x^2 - 5) = y * (x^2 + 1) * (x^2 - 5)
The correct result would be <span>y * (x^2 + 1) * (x^2 - 5).</span>
798 calories are in 6 10-ounce bottles of Apple juice. We have to calculate how many calories are in one 10-ounce bottle of Apple juice. We have just to divide 798 calories by 6: 798 : 6 = 133. Answer: There are 133 calories in one 10-ounce bottle of Apple juice
The first one, 4x is the slope and the +3 is the y-intercept
