Question

Evaluate.....................

Answer 1

Explanation:

Evaluate:

3^(-3)

We know that

Low of exponent intergal for,

a^-n = 1/a^n, so using this we get

→ 1/3^3

→ 1/(3*3*3)

→1/9*3

→1/27

Option (a) 1/27 is your correct answer.

Answer 2

3^-3 we can write if the power is in negative sign in fraction it will be positive like if a^-2=1/a2

so if the power of 3 is -3 like 3^-3 then we can write it as 1/3^3 or we can write 1/3*3*3

3^-3=1/27
