M 4/6 Distance Lesson #6:
Happy Monday everyone! Today you are taking your "TEST" on Transformations. Log into Castle learning and answer assignment "8RDL Transformations #2"
Once you start this assignment, it must be completed within 24 hours. Good luck!
Additional Notes: Today you are starting working with Exponents. An exponent is the small, raised number, also known as the power. It is attached to a larger number called the base. Each exponent refers to its individual base:
- 3*3*3*3*3 = 3^5
- 3*3*3*3*3*7*7 = 3^5*7^2
When a base is raised to a power of zero, the answer is always 1, except when the base is 0 itself, (which you don't have to be worried about):
- 3^0 = 1
- (-3)^0 = 1
- -3^0 = -1 *since the negative is not in parentheses with the 3, the problem really means -1*3^0 = -1*1 = 1
The new concept today is with Negative Exponents. Just like we cannot leave negative signs in denominators of fractions, we cannot leave exponents negative. To make a negative exponent positive, we have to rewrite the base using its reciprocal. Remember reciprocal is when we flip a fraction upside down:
- 2^-3 = (1/2)^3
- -7^-4 = (-1/7)^4
- (2/3)^-9 = (3/2)^9

Additional Notes: When bases are being divided, you keep the base and subtract the exponents. The classwork shows how you can expand the numerator and denominator then cancel out like terms. Be careful when there are negative exponents involved:
- 7^8 / 7^5 = 7^3 because 8-5=3
- 7^-8 / 7^5 = 7^-13 because -8-5=-13 we would then get rid of the negative exponent by doing the reciprocal: (1/7)^13
- 7^8 / 7^-5 = 7^13 because 8- -5= 8 + 5 = 13

Additional Notes: When bases are being multiplied, you keep the base and add the exponents. The classwork shows how you can expand the powers
- 7^8 * 7^5 = 7^13 because 8+5=3
- 7^-8 * 7^5 = 7^-3 because -8+5=-3 we would then get rid of the negative exponent by doing the reciprocal: (1/7)^3
- 7^8 * 7^-5 = 7^3 because 8+ -5= 8 - 5 = 3
- 7^-8 * 7^-5 = 7^-13 because -8+-5=-13 we would then get rid of the negative exponent by doing the reciprocal: (1/7)^13
