Express each of the following in exponential form:
(1) -1296/14641
(2) -125/343

Solution:

We have to express each of the given terms in exponential form.

(1) -1296/14641

We know, 1296 = 6 × 6 × 6 × 6 = 6⁴

We know, 14641 = 11 × 11 × 11 × 11 = 11⁴

Exponential form = -(6)⁴/11⁴

= -(6/11)⁴

(2) -125/343

We know, 125 = 5 × 5 × 5 = 5³

Also, 343 = 7 × 7 × 7 = 7³

Exponential form = -(5)³/7³

= -(5/7)³
