<span>Exponents are the repeated multiplication of a
number. It is represented by the formula of a^n where a is the number to be
repeated and n is the number of times the number is being multiplies by itself.
Also include the sign of the number, no matter how it is multiplied, it is
still important. In this problem, you have 4 as the repeated number. You can
see that it is multiplied by itself by two times. So you have (-4)^2.</span>

Step-by-step explanation:
It will take Katie 29 weeks to reach her goal and it will take Rebecca 28 weeks to reach her goal so Rebecca will finish one week before Katie.
Hope this helps!
A tautology will have an infinite number of solutions, as it is true for all possible values of the variable by definition.
Example: 3(x+2) = 3x+6
All other linear equations in one variable will have one solution, which may include values that are undefined or indeterminate.
Examples:
... 3x-2 = 7 . . . solution is x=3
... x = 0/0 . . . . solution is an indeterminate number
... x = 1/0 . . . . solution is undefined
39 inches = 3 feet 3 inches
42.5 inches = 3 feet 6 1/2 inches
61 3/4 inches - 5 feet 1 3/4 inches
