The value on the 15 th day can also be found by multiplying “2” over 14 times © Copyright all rights reserved to Homework depot:

W HAT ARE E XPONENTS ? Exponents are used to represent the multiplication of a constant over many times Rather than writing out the same constant over again, we can exponents to simplify the expression Write as a single exponent The number in the bottom is the Base The number at the top is the Exponent The entire expression is a “Power” ie: 2 to the power of 14 The base is the number that is being multiplied by The exponent is how many times you multiply the base by itself © Copyright all rights reserved to Homework depot:

P OWERS WITH N EGATIVE BASES If the base has a negative sign within brackets, then the base is negative If the negative sign is not within brackets or there are no brackets, then the base is positive, with a negative sign in front The product of two negative bases will become positive Base is -5 Base is 5, so only the “5” is squared and not the negative sign © Copyright all rights reserved to Homework depot:
