Answer:

[tex]1.61*10^{8} \\and\\3.3*10^{-7}[/tex]

Step-by-step explanation:

We can use properties of exponents to solve these equations. Remember that when multiplying exponents, we 'add' them.

--------------------------------------

[tex](2.3*10^{1})(7*10^{6})= \\16.1*10^{7}=\\1.61 *10^{8}[/tex]

For the next question:

[tex](1.1*10^{-5})(3*10^{-2})=\\ 3.3*10^{-7}[/tex]

These are your answers!

Answer:

see explanation

Step-by-step explanation:

Using the rule of exponents

[tex]a^{m}[/tex] × [tex]a^{n}[/tex] = [tex]a^{(m+n)}[/tex]

Given

2.3 × [tex]10^{1}[/tex] × 7 × [tex]10^{6}[/tex]

= 2.3 × 7 × [tex]10^{(1+6)}[/tex]

= 16.1 × [tex]10^{7}[/tex]

= 1.61 × [tex]10^{1}[/tex] × [tex]10^{7}[/tex]

= 1.61 × [tex]10^{8}[/tex]

-----------------------------------

1.1 × [tex]10^{-5}[/tex] × 3 × [tex]10^{-2}[/tex]

= 1.1 × 3 × [tex]10^{(-5-2)}[/tex]

= 3.3 × [tex]10^{-7}[/tex]
