Step-by-step explanation:

Answer 2

Answer:-)

(a) -8

______________

(b) -4/25

_______________

(c) 4^[5+(-7)] by(x^a*x^b=x^(a+b)

=4^-2

_______________

(d) 2^[5-(-6)] by(x^a÷x^b=x^(a-b)

2^(-11)

_______________

(e)[(2×3)^-1]^-1

= (2×3)^-1×-1

= (2×3)

=6

_______________

(f)(1/4+1/8)÷(2/3)^-1

=(1/4+1/8)÷3/2

=(2+1/8)÷3/2

=3/8÷3/2

=3/8×2/3

=1/4

________________

(g)(1/5)^-1+(1/4)^-1

=5+4

=9

________________

(h)(1/5)^-2×(5/7)-2

=(5/1×7/5)^2

=7/1^2

=49

________________

(i)(-2/5)^-4×(-2/5)^2

=(-2/5)^-4+2

=(-2/5)^-2

=(-5/2)^2

= -25/4
