Question

If a = 3 and b = -2, then find the value of a^a + b^b. Please answer with steps.​

Answer 1

Step-by-step explanation:

a^a +b^b = 3³+(-2)^-2

= 27+ 1/(-2)²

=27+1/4

take LCM

=(108+1)/4 = 109/4

Answer 2

Answer:

109/4

Step-by-step explanation:

To calculate a^a + b^b first place the values of a and b

ATP,

$a^{a\\}$ + $b^{b}$

= $3^{3}$ + $(-2)^{-2}$

= 27 + $\frac{1}{(-2)^2}$                                                                                         ($a^{-m}$ = $\frac{1}{a^m}$)

= 27 + $\frac{1}{2^2}$                                                                                  (Since $(-2)^{2}$ = $2^{2}$)

= 27 + $\frac{1}{4}$

= 109/4
