Answer:

The solution for the given expression is
x^(38) , i.e option C

Explanation:

Given expression as :


((x^(6)* x^(10))/(x^(-3)))^(2)

Now, From the common radix method

∵ In multiplication of radix , if the radix is same , then power is added

I.e
x^(6)* x^{10 =
x^(6+10)

Or ,
x^(6)* x^{10 =
x^(16)

Now, The expression can be written as


((x^(16))/(x^(-3)))^(2)

And In Division of radix , if the radix is same , then power is subtracted

So,
(x^(16))/(x^(-3))

Or,
x^(16 - (-)3)

Or,
x^(16 + 3)

or,
x^(19)

∴ The expression is now


(x^(19))²

Now, again this is written as


x^(19) ×
x^(19)

I.e here again the radix is same and in multiple for, so, power is added


x^(19) ×
x^(19) =
x^(19+19)

I.e
x^(19) ×
x^(19) =
x^(38)

Hence The solution for the given expression is
x^(38) , i.e option C . Answer
