Question

Solve it please, it's urgent। ​

Answer 1

Answer:

I didn't see what is your question so please mark

Answer 2

Step-by-step explanation:

can't solve all here but can hint you how to attempt

x^(-2)+x^(-3) = 1

now x^ (-2) will be written as (1/x)^2 or 1/x^2

similarly x^(-3) will be written as 1/x^3

so solution of first problem is

1/x^2 + 1/x^3 = 1 ..(we can leave the solution here also)

x^3 + x^2 = x^2*x^3

x^3 + x^2 = x^5

in all the problems where exponent of a letter/number is negative. substitute it with reciprocal of the number (1/a for a and vice versa) with positive exponent as explained in above example

If the exponent is under root (√) first convert it into rational exponent and then apply the same procedure. I'll solve one such problem for your clarity.

the solution is attached.

hope you find it useful.
