1. Mathematics 7 second quarter

2.   base exponent   Power of    

3. The laws of exponents PRODUCT RULE QUOTIENT RULE NEAGATIVE EXPONENT RULE ZERO EXPONENT RULE POWER RULE POWER OF THE PROUCT RULE POWER OF THE QUOTIENT RULE

4. LEARNING OBJECTIVES At the end of the lesson, we are expected to: a. derives the laws of exponents b. illustrates the laws of exponent; and c. appreciate the concepts of laws of exponents as applied in real-life situation.

5. The laws of exponents a. Product Rule: If and are real numbers, then . b. Quotient Rule: b. 1. General rule: If and are real numbers and , then . b. 2. Definition of Negative Exponent: If and are real numbers and , then or . b. 3. Definition of Zero Exponent: If , then .  

6. The laws of exponents c. Power Rule: c. 1. General Rule: If and are real numbers, then . c. 2. Power of the Product Rule: If and are real numbers, then . c. 3. Power of the Quotient Rule: If and are real numbers and , then .  

7. Scientific notation Scientific notation is in the form of , where and is an integer.  

8. science Photon , also called light quantum , minute energy packet of electromagnetic radiation . The concept originated (1905) in Albert Einstein ’s explanation of the photoelectric effect , in which he proposed the existence of discrete energy packets during the transmission of light. Earlier (1900), the German physicist Max Planck had prepared the way for the concept by explaining that heat radiation is emitted and absorbed in distinct units, or quanta . The concept came into general use after the U.S. physicist Arthur H. Compton demonstrated (1923) the corpuscular nature of X-rays . The term photon (from Greek phōs , phōtos , “light”), however, was not used until 1926. A photon travels at approximately meters per second. If a year is approximately seconds, how far would be a photon travel in one year?  

9. economics Last July 23, 2020, it was reported by the ABS-CBN News that almost B or Php386.6B ( is the dept of the Philippines from different international banks to fight against COVID-19 and interest is not yet being added to it. How can the Philippines pay off this dept? What is the effect of this dept to the people of the Philippines? Tax is a compulsory financial charge imposed to taxpayer by a government organization in order to fund government spending and various public expenditures. According to the National QuickStat (NQS), the total population as of 2015 has an estimation of 100.981 million ( ) people, reported by the Philippine Statistics Authority (PSA) as of December 2020. Using this estimation, calculate the per person share of the national dept. Write your answer with 4 significant digits.  

10. Direction. Simplify the following with positive exponents. 1. 2. 3. 4. 5.
