Question

Given that a*b = 2ab - 3b. Determine 2*(3*5)​

Answer 1

15

Problem:

Given that a*b = 2ab - 3b. Determine 2*(3*5)​

Explanation:

First we find 3*5 using rule a*b = 2ab - 3b.

3*5=2(3)(5)-3(5)

3*5=30-15

3*5=15

Now we are left with 2*15 in which we will still use the rule a*b=2ab-3b.

2*15=2(2)(15)-3(15)

2*15=60-45

2*15=15

Therefore, 2*(3*5)=15.
