Find the value of the expression 0.5^10/0.5^7

SIZIF [17.4K]

Answer:

The solution is:

$\frac{0.5^{10}}{0.5^7}=0.125$

Step-by-step explanation:

Given the expression

$0.5^{10}\div 0.5^7$

Solving

$\frac{0.5^{10}}{0.5^7}$

$\mathrm{Apply\:exponent\:rule}:\quad \frac{x^a}{x^b}=x^{a-b}$

$\frac{0.5^{10}}{0.5^7}=0.5^{10-7}$

$\mathrm{Subtract\:the\:numbers:}\:10-7=3$

$=0.5^3$

$=0.125$ ∵ $0.5^3=0.125$

Therefore, the solution is:

$\frac{0.5^{10}}{0.5^7}=0.125$

Which of these is a unit of density?

Naddika [18.5K]

<h3><u>Answer:- </u></h3>

$\longrightarrow \textsf{The unit of density is\;}$ $\sf kg/m^3$

<h3><u>Solution</u> :-</h3>

$\green{ \underline { \boxed{ \sf{Density = \frac{Mass}{Volume}}}}}$

$\longrightarrow$ The unit of mass is kg and unit of Volume is m³ . Since density is division of mass by volume , the corresponding units will also get divided and unit of density would come out to be kg/m³

<u>Some basic </u><u>derived </u><u>Units :- </u>

area => m²
volume cubic meter => m3
speed meter per second => m/s
acceleration => m/s²
mass density meter => kg/m3
specific volume cubic meter per kilogram m³/kg
