o Compare the parts of an exponential expression with a radical expression.

o Explain what a perfect square is and give some examples.

o Describe the process of rationalizing the denominator

|(1) Consider the exponential expression 3^(1/2). This has base 3 and an exponent 1/2. | |The denominator of the exponent is 2. This is the order. | | The equivalent radical expression is √3. Here, √ is called the radical sign. 3 is called the radicand. Since √3 means square root of 3, the order is 2. | | Another example is 10^(1/3). This has base 10 and an exponent 1/3. | |The denominator of the exponent is 3. This is the order. | | The equivalent radical expression is 3√10 (The 3 is over the radical sign). 10 is the radicand. Since 3√10 means cube root of 10, the order is 3. | | | |(2) A perfect square is a number whose square root is a whole number. For example, 25 and 64 are prefect squares since √25 = 5 and √64 = 8 are both whole numbers. | |On the other hand 15 is not a perfect square since √15 = 3.87 is not a whole number. | |In Algebra also, a perfect square expression is one whose square root will have no radical sign anywhere in it. For example, x^2 is a perfect square because its | |square root is x (no radical sign here). On the other hand, x^3 is not a perfect square because √(x^3) = x √x...

...Exponential Smoothing Forecasting Method with Naïve start
Formula: Ft = α (At-1) + (1 – α) (Ft – 1) where:
Ft Forecast for time t
Ft – 1 Past forecast; 1 time ahead or earlier than time t
At-1 Past Actual data; 1 time ahead or earlier than time t
α (read as alpha) as a smoothing...

...In mathematics, an algebraic expression is an expression built up from constants, variables, and a finite number of algebraic operations (addition, subtraction, multiplication, division and exponentiation by an exponent that is a rational number).[1] For example, is an algebraic expression. Since taking the square root is the same as raising to the power ,
is also an algebraic expression.
A rational expression is an...

...On the outside you would think that a blizzard would be very different than a hurricane. They are quite similar in their makeup and destructive powers. They are just two of the natural disasters that our planet has to offer and seem to becoming more common. Hurricanes and blizzards are two of the worst natural disasters that are like twisted sisters in Mother Natures destructive family. I will show how they are so closely related from their startup to finish.
Blizzards are...

...1 Compare, contrast and evaluate the contribution made by Solomon Asch and Muzafer Sherif to our understanding of conformity.
Conformity is one’s tendency to tweak his own perception, opinions or behaviour in ways that are consistent with group norms which are patterns of action which people feel compelled to subscribe to because they appear to be appropriate, moral or ethical (Kassin et al, 2014). Muzafer Sherif and Solomon Asch conducted two classic studies that...
