Question

53.(51+4)+53.(49+91)+53

Answer 1

\(53.\left(51+4\right)+53.\left(49+91\right)+53\\ =53.55+53.140+53.1\\ =53.\left(55+140+1\right)\\ =53.196\\ =10388.\)

Answer 2

\(53\cdot\left(51+4\right)+\left(49+91\right)+53\)
\(=53\cdot55+53\cdot140+53\cdot1\)

\(=53\cdot\left(55+140+1\right)\)

\(=53\cdot196\)

\(=53\cdot\left(200-4\right)\)

\(=53\cdot200+53\cdot4\)

\(=10600-212\)

\(=10388\)

Answer 3

\(53.\left(51+4\right)+53.\left(49+91\right)+53\)

\(=53.55+53.140+53\)

\(=53.\left(55+140+53\right)\)

\(=53.248\)

\(=13144\)

Answer 4

$53\cdot \left(51+4\right)+\left(49+91\right)+53$
$=53\cdot 55+53\cdot 140+53\cdot 1$

$=53\cdot \left(55+140+1\right)$

$=53\cdot 196$

$=53\cdot \left(200-4\right)$

$=53\cdot 200+53\cdot 4$

$=10600-212$

$=10388$
