$\bold{\huge{\pink{\underline{ Solutions }}}}$

<u>Here</u><u>, </u><u> </u><u>we </u><u>have </u><u>to </u><u>expand </u><u>the </u><u>given </u><u>expression</u><u>s</u><u> </u><u>and </u><u>simplify </u><u>each </u><u>one </u><u>of </u><u>them</u>

<h3><u>Solution</u><u> </u><u>1</u><u> </u><u>:</u><u>-</u></h3>

$\bold{m(4 + p) + p( 3 + m) }$

$\sf{4×m + m× p + p×3+ m × p}$

$\sf{4m + mp + 3p + mp }$

$\bold{\red{ 2mp + 4m + 3p}}$

Hence, Your answer is 2mp + 4m + 3p

<h3><u>Solution </u><u>2</u><u> </u><u>:</u><u>-</u></h3>

$\bold{4r(3+ 4p) + 3p( 8 - r) }$

$\sf{4r× 3+ 4r × 4p + 3p× 8 - 3p × r}$

$\sf{12r + 16rp + 24p - 3rp }$

$\sf{12r + 24p + 13rp }$

$\bold{\red{13rp + 24p + 12r }}$

Hence, your answer is 13rp + 24p + 12r

<h3><u>Solution </u><u>3</u><u> </u><u>:</u><u>-</u></h3>

$\bold{(3 + 2h)(5 + 3h )}$

$\sf{3(5 + 3h) + 2h(5 + 3h }$

$\sf{15 + 9h + 10h + 6h² }$

$\sf{15 + 19h + 6h²}$

$\bold{\red{6h² + 19h + 15}}$

Hence, your answer is 6h² + 19h + 15

<h3><u>Solution </u><u>4</u><u> </u><u>:</u><u>-</u></h3>

$\bold{(3 + 4y)(5y - 1 ) }$

$\sf{3(5y - 1 ) + 4y(5y - 1) }$

$\sf{15y - 3 + 20y² - 4y }$

$\sf{11y - 3 + 20y²}$

$\bold{\red{20y² + 11y - 3 }}$

Hence, your answer is 20y² + 11y - 3

<h3><u>S</u><u>olution </u><u>5</u><u> </u><u>:</u><u>-</u></h3>

$\bold{(2n - 3p )(3p - 2m ) }$

$\sf{2n(3p - 2m) -3p(3p - 2m) }$

$\sf{ 6np - 4nm - 9p² + 6mp }$

$\bold{\red{- 9p² - 6mp - 4nm + 6np }}$

Hence, your answer is - 9p² - 6mp - 4nm + 6np

Benford’s law states that the probability that a number in a set has a given leading digit, d, is

Scilla [17]

<span>Benford’s law states that the probability that a number in a set has a given leading digit, d, is
P(d) = log(d + 1) - log(d)</span>
The division property of logarithm should be use to make it as a single logarithm
P(d) = log ( (d + 1)/ d)
So the probability that the number 1 is the leading digit is
P(1) = log ( ( 1+1)/ 1)
P(1) = log ( 2)
<span>P(1) = 0.301</span>
