Question

If a = 1, and b = 2, find $a^{b} + b^{a}$

Open in App

Solution

We have,
$a = 1, b = 2$

Since, $a^{b} + b^{a}$
$= 1^{2} + 2^{1}$
$= 1 + 2$
$= 3$

Hence, this is the answer.

Q. If a = 1, b = 2 then find the value of (a^b + b^a)^–1.

a = - 1

b = 2,

\frac{a^{b} \times b^{a}}{b - 2 a}

a^{b} = 4 - a b

b^{a} = 1
