Question

if a = 2 b= 3 then find a power b +b power a power -1​

Answer 1

Answer:

Here, we have given

⟹ a = 2

⟹ b = 3

☑ Then, we have to find the value of

${a}^{b} + {b}^{ {a}^{( - 1)} }$

we know the identity,

${a}^{ {m}^{n} } = {a}^{m \times n}$

Therefor ,

${a}^{b} + {b}^{( - a)}$

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

$= 8 + (0.11)$

$= 8.11$

Therefor a power b +b power a power -1 =

$\boxed{\textbf{\large{8.11}}}$
