Question

simplify the following by using appropriate properties -52 × (102) and 783 × (-92) + (-783) × 3​

Answer 1

Answer:

Step-by-step explanation:

1) we can simplify by the distributive property

now - 52 x (102)

= -52 x (100+2)

= -52 x 100 + (-52) x 2

= -5200 +(-104)

= - 5304

now 783 x(-92) + (-783) x 3

= 783 x (-100 + 8)  + (-783) x 3

= -78300+ 6264 + (-2349)

= -78300 - 2349 + 6264

= -74385
