Negative number raised to an odd power is negative

To show this we begin with (-7)5 ,a negative number raised to an odd exponent:

(-7)5 can be written as (-7)•(-7)•(-7)•(-7)•(-7)

Now, using the rule that says minus times minus is plus, (-7)5 can be written as (49)•(49)•(-7) which is a negative number.

We showed that (-7)5 is a negative number

Using the same arguments as above, replacing (-7) by any negative number, and replacing the exponent 5 by any odd exponent, we proved which had to be proved

Rewriting the whole as an Equivalent Fraction

6.1 Subtracting a whole from a fraction

Rewrite the whole as a fraction using 7 as the denominator :

-73 -73 • 7

-73 = ——— = ———————

1 7

Equivalent fraction : The fraction thus generated looks different but has the same value as the whole

Common denominator : The equivalent fraction and the other fraction involved in the calculation share the same denominator

Adding fractions that have a common denominator :

6.2 Adding up the two equivalent fractions

Add the two equivalent fractions which now have a common denominator

Combine the numerators together, put the sum or difference over the common denominator then reduce to lowest terms if possible:

n - ( -73 • 7) n + 2401

—————————————— = ————————

When a fraction equals zero :

7.1 When a fraction equals zero ...

Where a fraction equals zero, its numerator, the part which is above the fraction line, must equal zero.

Now,to get rid of the denominator, Tiger multiplys both sides of the equation by the denominator.

Here's how:

n+2401

—————— • 7 = 0 • 7

7

Now, on the left hand side, the 7 cancels out the denominator, while, on the right hand side, zero times anything is still zero.

The equation now takes the shape :

n+2401 = 0

Solving a Single Variable Equation:

7.2 Solve : n+2401 = 0

Subtract 2401 from both sides of the equation :

n = -2401

One solution was found :

n = -2401
