a. Add these numbers in Scientific Notation.

2.84 ๐‘ฅ 104 + 6.05 ๐‘ฅ 104=

2.84 ๐‘ฅ 10^4 + 6.05 ๐‘ฅ 10^4 = 9.89 ๐‘ฅ 10^4

b. Subtract these numbers in Scientific Notation.

7.41 ๐‘ฅ 10โˆ’7 โˆ’ 3.67 ๐‘ฅ 10โˆ’7

7.41 ๐‘ฅ 10^(-7) โˆ’ 3.67 ๐‘ฅ 10^(-7) = 3.74 ๐‘ฅ 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 ๐‘ฅ 10โˆ’6 รท 18.4 ๐‘ฅ 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 ๐‘ฅ 10^(-6) รท 18.4 ๐‘ฅ 10^2 = (36.8 รท 18.4) * (10^(-6 - 2))
= 2 * 10^(-6 - 2)
= 2 * 10^(-8)
= 2๐‘ฅ 10^(-8)
