Answer 1

Answer:

Question:-

distance between the earth and the moon is approximately 384000 kilometre Express this distance in metres in exponential form notation

384000 km

m=384000×1000

=384000000

=384×10$^6$

Answer 2

Answer:

Mean Distance To Moon From Earth in scientific notation = $\sf{3.844\times \:10^8}$ m

Step-by-step explanation:

Mean Distance To Moon From Earth : $\sf{384,\:400,\:000}$ m

$\mathrm{Scientific\:notation\:is\:in\:the\:form\:}a\times 10^b\:\mathrm{where}\:\:1\le a<10\mathrm{\:and\:}b\mathrm{\:is\:an\:integer.}\:$

$\to\mathrm{Move\:the\:decimal\:point\:to\:the\:\mathrm{left}\:to\:create\:a\:new\:number\:from\:1\:up\:to\:10}$

$\sf{a=3.84400000}$

$\to\mathrm{Count\:the\:number\:of\:times\:you\:moved\:the\:decimal\:point}$

$\sf{b=8}$

$\sf{=3.84400000\times 10^8}$

$\to\mathrm{Remove\:trailing\:zeroes}$

$\sf{=3.844\times \:10^8}$

∴ Mean Distance To Moon From Earth in scientific notation = $\sf{3.844\times \:10^8}$ m
