Question

Write the algebraic form of the general principle used to do the following calculation easily
68x25 + 32×25​

Answer 1

Answer:a×b+b×c=b(a+c)

Step-by-step explanation:

25(32+68)=2500

Answer 2

Answer:

a * ( b + c)  = a*b  + a * c

2500

Step-by-step explanation:

Need to calculate :

68x25 + 32×25​

Principle to be used :

a * ( b + c)  = a*b  + a * c

68x25 + 32×25

= 25 * 68  + 25 * 32

comparing with

a*b  + a * c

a = 25   b = 68   c = 32

= 25 * ( 68 + 32)

= 25 * 100

= 2500
