Question

Find the following product using distributive property
a> 738×98 b.) 169 X 1003
c.) 165×99 + 165​

Answer 1

Answer:

c.) 165×99 + 165is the correct answer

Answer 2

$\underline{\pink{ Distributive \: Property :}}$

$a,b,c \: are \: integers ,$

$\boxed{\blue{ a(b+c) = a \times b + a \times c }}$

$a) 738 \times 98$

$= 738 \times (100-2)$

$= 738 \times 100 - 738 \times 2$

$= 73800 - 1476$

$= 72324$

Therefore.,

$\red{ a) 738 \times 98}\green {= 72324}$

$b) 169\times 1003$

$= 169 \times (1000+3)$

$= 169 \times 1000 + 169 \times 3$

$= 16900 + 507$

$= 17407$

Therefore.,

$\red{ b) 169 \times 1003}\green {= 17407}$

$c) 165\times 99 + 165$

$= 165\times 99 + 165 \times 1$

$= 165( 99 + 1 )$

$= 165 \times 100$

$= 16500$

$\red{c) 165\times 99 + 165}\green {= 16500}$
