Question

evaluate using identities : a) 102×106. ___ b) (4a -b +2c)^2. c); (1/x +y/3 )^3​

Answer 1

Answer:10812

Step-by-step explanation:

102 X 106=

(100 + 2)(100+6)

This is in the form identity III [ (x+a)(X+b) = x^2 + (a+b)x + ab

= 100^2 + (6+2)100 + 2(6)

10000+8(100) +12

10000+800 +12

10800 + 12

10812
