Answer 1

-45×107 is not same as (-40-5

Answer 2

$Given \: -45 \times 107$

$a) -45 \times ( 100 + 7 ) = -45 \times 107 \: \blue { ( True ) }$

$b) (-45) \times7 + (- 45)\times 10 \\= (-45) \times (7 + 10) \\= -46 \times 17 \pink {\neq -}45 \times 107 \\ \therefore This \: statement \:is \: \red { ( False ) }$

$c) -45 \times 7 + 100 \pink { \neq } -45 \times 107$

$\therefore This \: statement \:is \: \red { ( False ) }$

$d) (-40 - 5 ) = -45 \pink { \neq } -45 \times 107$

$\therefore This \: statement \:is \: \red { ( False ) }$
