Question

(5^-1 - 10^-1)^-1 + (3^-1 - 5^-1 - 5^-1) ^-1 find value​

Answer 1

Answer:

Step-by-step explanation:

[(5^-1) - (10^-1)]^(-1) + [(3^-1) - (5^-1) - (5^-1)]^(-1)

= (0.2 - 0.1)^(-1) + (1/3 - 0.2 - 0.2)^(-1)

= (0.1^-1) + [(-1/15)^-1]

= 10 + (-15)

= -5

Answer 2

Answer:

(5^-1 - 10^-1)^-1 + (3^-1 - 5^-1 - 5^-1)^-1

(1/5-1/10)^-1 + (1/3-1/5-1/5)^-1

[(2-1)/10]^-1 + (1/3-2/5)^-1

(1/10)^-1 + [(5-6)/15]^-1

10+ (-1/15)^-1

10+(-15)

10-15

-5
