Question

NO WRONG ANSWERS WRONG ANSWER WILL REPORTED​

Answer 1

As we know that

i ) if degree of a negative number is even number then the solution is poisitive [i.e., (-a)^n is even if n is even number]

a) (-2)^6 = 64

b) 2^3 x (-3)^2 = 8 x 9 = 72

c) (-1)^6 = 1 {as n is even answer is positive}

d) (-1)^7 = -1 {as n is odd answer is negative}

e) (-2)^5 x (-5)^6 = -32 x 3125

f) (-2)^3 x (-5) = -8 x -5 = 40

g) yes it is true because (-3)^3/2^3 = -27/8=(-3/2)^3
