Question 29
Some equations are solved on the basis of a certain system. Find the correct answer for the unsolved equation on that basis.
2*3 = 17; 3*4 = 145; 5*2 = ?
Solution
The pattern followed is that $$a*b=a^b+b^a$$
Eg = 2*3 = $$2^3+3^2=8+9=17$$
and 3*4 = $$3^4+4^3=81+64=145$$
Similarly, 5*2 = $$5^2+2^5=25+32=57$$
=> Ans - (C)
