Question

solve it one word answer please​

Answer 1

Mean = 5 ,a^4*a^7=a^11 and circumference of the circle is 2*pi*r where r is radius

Answer 2

Answer:

$\bold\red{Solution}$

i - $\bold\blue{The\:mean\:of\:9,16,5,4\:and\:11\:is\:=\:?}$

Solution -

$\boxed {Mean = \frac{Sum\:of\:all\: observations}{No.\:of\: observations}}$

So,

Let the Mean be x

$\implies {x = \frac{9+16+5+4+11}{5}}$

$\implies {x = \frac{45}{5}}$

$\implies {x\:=\:9}$

ii -

${a^4 × a^7=?}$

$\bold\green{Formula}$

${a^m * a^n=a^m^+^n}$

So,

${a^4 * a^7=a^4^+^7}$

$\implies {a^1^1}$

iii -

$\bold\blue{The\: Circumference\:of\: Circle\:is\:2πr.}$
