Answer:
Step-by-step explanation:
Let be "s" the length in meters of the short piece and "l" the lenght in meters of the long piece.
Set up a system of equations:
Apply the Substitution Method to solve the system. Substitute the second equation into the first equation and solve for "l":
Susbstitute the value of "l" into the second equation in order to find the value of "s". This is:
The expression which is equal to the m times, m times, m times, m times, m rewritten in exponential form as,
The exponent or power of a number represent the multiplication of the that number to the power times.
Let suppose a number 2 has the power 2. Then it will be equal to,
Similarly, 3 times of number 2 equal to the number 2 with exponent 3.
The expression is m times, m times, m times, m times, m. It can be written as,
The number m is total 5 time multiply by itself. Thus, the exponential form of the above equation is,
The expression which is equal to the m times, m times, m times, m times, m rewritten in exponential form as,
