Question

if * is an operation such that for any two integers a and b. a*b (-2), Find the value of : (i): (-3) * (-5) (i): 2 *(-3) (iii): (-5) * (-3) Ifa * b = b *a? - ab + 1) (iv): (-3)* 2​

Answer 1

Answer:

Given, a

∗

b=a×b+(a×a+b×b)

So.

(i)

we put a=(−3) and b=(−5)

(−3)∗(−5)=(−3)×(−5)+[(−3)×(−3)+(−5)×(−5)]

=15+(9+25)=15+34=49

(ii)

Similarly, a=−6,b=2

(−6)∗2=(−6)×2+[(−6)×(−6)+2×2]

=−12+(36+4)

=−12+40=28

Answer 2

Answer:

Answer:(1) = -6 ,(2) = -6, (3) =Yes
