Question

please give me answer step by step i need second part​

Answer 1

Step-by-step explanation:

use law of exponents , a^-1 = 1/a

so 5^-1 =1/5

and 10^-1 = 1/10

now the equation will be (1/5 - 1/10)^-1

now take the lcm , ( 2/10 - 1/10) ^-1

which is equal to (1/10)^-1

now if a^-1 =1/a

so a = 1/(a^-1)

similarly (1/10)^-1 = 10

so the answer is 10

hope it helped you ,if yes then please thank the answer and mark as brainliest answer if you understood it
