QuestionMultiply. Write in scientific notation, and then write the result in standard forn 1.4.1) (3.4×107)×(8.4×105)=\left(-3.4 \times 10^{-7}\right) \times\left(8.4 \times 10^{5}\right)= 1.4.2) (70×104)×(60×106)=\left(70 \times 10^{-4}\right) \times\left(60 \times 10^{6}\right)=
Divide. Write in scientific notation, and then write the result in standard form. 1.4.3) 4.10×102(2.05×104)=\frac{4.10 \times 10^{-2}}{\left(-2.05 \times 10^{4}\right)}= 1.4.4) 1.14×1073.8×103=\frac{1.14 \times 10^{7}}{3.8 \times 10^{-3}}=

Studdy Solution
Convert 0.3×10100.3 \times 10^{10} to proper scientific notation and standard form.
0.3×1010=3×101×1010=3×109 0.3 \times 10^{10} = 3 \times 10^{-1} \times 10^{10} = 3 \times 10^{9}
3×109=3000000000 3 \times 10^{9} = 3000000000
Solution: 1.4.1) Scientific notation: 2.856×101-2.856 \times 10^{-1}, Standard form: 0.2856-0.2856.
1.4.2) Scientific notation: 4.2×1054.2 \times 10^{5}, Standard form: 420000420000.
1.4.3) Scientific notation: 2×106-2 \times 10^{-6}, Standard form: 0.000002-0.000002.
1.4.4) Scientific notation: 3×1093 \times 10^{9}, Standard form: 30000000003000000000.
