2.84 𝑥 104 + 6.05 𝑥 104=

Answer 1

b. Subtract these numbers in Scientific Notation.
7.41 𝑥 10−7 − 3.67 𝑥 10−7

Answer 2

c. Multiply these numbers in Scientific Notation.

6.92 * 10^9 * 2.59 * 10^3

Answer 3

d. Divide these numbers in Scientific Notation.
36.8 𝑥 10−6 ÷ 18.4 𝑥 102

Answer 4

2.84 𝑥 10^4 + 6.05 𝑥 10^4 = 9.89 𝑥 10^4

Answer 5

7.41 𝑥 10^(-7) − 3.67 𝑥 10^(-7) = 3.74 𝑥 10^(-7)

Answer 6

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

Answer 7

To divide numbers in scientific notation, divide the coefficients and subtract the exponent of the divisor from the exponent of the dividend.

36.8 𝑥 10^(-6) ÷ 18.4 𝑥 10^2 = (36.8 ÷ 18.4) * (10^(-6 - 2))
= 2 * 10^(-6 - 2)
= 2 * 10^(-8)
= 2𝑥 10^(-8)
