Question

by what number should (1/2) power -1 be multiplied so that the product is equal to (-4/7) power -1 ?​

Answer 1

Answer:

-7/8

Step-by-step explanation:

(1/2)^-1 = 2^1

(-4/7)^-1 = (-7/4)^1

we can ignore power of 1

so,

2 × x = -7/4

2x × 4 = -7

8x = -7

x = -7/8

Answer 2

Answer:

(-7/8)

Step-by-step explanation:

(1/2)^-1=2

(-4/7)^-1=(-7/4)

(-7/4)/2=-7/4*2

=(-7/8)
