a. Add these numbers in Scientific Notation.
2.84 ๐ฅ 104 + 6.05 ๐ฅ 104=
2.84 ๐ฅ 10^4 + 6.05 ๐ฅ 10^4 = 9.89 ๐ฅ 10^4
b. Subtract these numbers in Scientific Notation.
7.41 ๐ฅ 10โ7 โ 3.67 ๐ฅ 10โ7
7.41 ๐ฅ 10^(-7) โ 3.67 ๐ฅ 10^(-7) = 3.74 ๐ฅ 10^(-7)
c. Multiply these numbers in Scientific Notation.
6.92 * 10^9 * 2.59 * 10^3
To multiply numbers in scientific notation, you can multiply the coefficients and add the exponents of the powers of 10.
6.92 * 10^9 * 2.59 * 10^3 = (6.92 * 2.59) * (10^9 * 10^3)
= 17.9128 * 10^(9+3)
= 17.9128 * 10^12
= 1.79128 * 10^13
d. Divide these numbers in Scientific Notation.
36.8 ๐ฅ 10โ6 รท 18.4 ๐ฅ 102
To divide numbers in scientific notation, divide the coefficients and subtract the exponent of the divisor from the exponent of the dividend.
36.8 ๐ฅ 10^(-6) รท 18.4 ๐ฅ 10^2 = (36.8 รท 18.4) * (10^(-6 - 2))
= 2 * 10^(-6 - 2)
= 2 * 10^(-8)
= 2๐ฅ 10^(-8)
