My Answers:-
1. 6.2*10^7
2. -3,050,000
3. 8.9*10^-7
4. 5.782*10^9
5. I rally don't understand this one!!
Plzz help me fast!!
correct on the first four.
On the fifth, do the exponents first
7.2/4.3 x E (-5+3)
then the division
1.7E-2 or in standard .017
i still didn't understand what u wrote for 5!
Sure! Let's go through each question one by one:
1. To convert 62,000,000 into scientific notation, we need to move the decimal point to the left until we have a number between 1 and 10. Count the number of places you moved the decimal point, and that will be the exponent of 10. In this case, we move the decimal point 7 places to the left, so the answer is 6.2 * 10^7.
2. To convert -3.05 * 10^6 into standard notion, we simply expand the scientific notation. In this case, the exponent is -6, so we move the decimal point 6 places to the left. The answer is -3,050,000.
3. To convert 0.00000089 into scientific notation, we need to move the decimal point to the right until we have a number between 1 and 10. Count the number of places you moved the decimal point, and that will be the exponent of 10. In this case, we move the decimal point 7 places to the right, so the answer is 8.9 * 10^-7.
4. To simplify (9.8 * 10^2) * (5 * 9 * 10^7), we can multiply the numbers outside the parentheses and combine the exponents of 10. The result is (9.8 * 5 * 9) * (10^2 * 10^7) = 441 * 10^9 = 4.41 * 10^11.
5. To simplify (7.2 * 10^-5) / (4.3 * 10^-3), we can divide the numbers outside the parentheses and subtract the exponents of 10. The result is (7.2 / 4.3) * (10^-5 / 10^-3) = 1.674 * 10^-2.
I hope this helps! Let me know if you have any further questions.
