चूक किंवा बरोबर

उत्तर

This statement is True.

Explanation:

Taking LHS, we have

`((-3)/5)^100 = ((-1 xx 3)/5)^100`  ......[∵ –3 = –1 × 3]

= `((-1)^100 xx 3^100)/5^100`  ......[∵ (a × b)m = am × bm]

= `(1 xx 3^100)/5^100`  ......[∵ (–1)n = 1, if n is even]

= `3^100/5^100`

Now, taking RHS, we have `(-3^100)/(-5^100) = 3^100/5^100`  ......`[(∵ "if both numerator and denominator have"),("negative sign,then it is cancelled out")]`

∴ LHS = RHS

Hence, `(-3^100)/5 = (-3^100)/(-5^100)`
