\text{The scientific notation:}\\\\a\times10^n\\\\1\leq a


a.\\(5\times10^3)\times(3.5\times10^{-1})=(5\times3.5)\times(10^3\times10^{-1})\\\\=15.75\times10^{3+(-1)}=15.75\times10^2=1.575\times10\times10^2\\\\=1.575\times10^{1+2}=\boxed{1.575\times10^3}

b.\\(8\times10^2)\div(4\times10^3)=(8\div4)\times(10^2\div10^3)=2\times10^{2-3}\\\\=\boxed{2\times10^{-1}}

c.\\(6\times10^{-3})^2=6^2\times(10^{-3})^2=36\times10^{-3\cdot2}=36\times10^{-6}=3.6\times10\times10^{-6}\\\\=3.6\times10^{1+(-6)}=\boxed{3.6\times10^{-5}}

Used:\\\\a^n\times a^m=a^{n+m}\\\\a^n\div a^m=a^{n-m}\\\\(a^n)^m=a^{n\cdot m}

Solution set for [4-x/2]=8
vovikov84 [41]

Answer:

x =   - 8

Step-by-step explanation:

(4 -  \frac{x}{2} ) = 8

-  \frac{x}{2}  = 8 - 4

-  \frac{x}{2}  = 4

- 2 \times (  - \frac{x}{2} ) =  - 2 \times 4

−1 \times (−x)=−2 \times 4

x=−2 \times 4

x =  - 8

What is the value of x? ASAP please
Vikentia [17]
All triangles have a total of 180° in them.

So to find x, simply take 50° and 100° from 180°:

x = 180 - 100 - 50
= 30°

So x = 30°, and thus option D
