Question

EXPONENTIAL FORM


plz do it very urgent​

Answer 1

Answer:

(2/5)^-6

Step-by-step explanation:

(2/5)^-2 x (2/5)^-2 x (2/5)^-2

Since the bases are same, we will calculate the powers separately and then write it with the base as common.

= (-2) + (-2) + (-2) ( LAW - a^c x a^d = a^c+d)

= (-2 -2 -2)

= (-6)

Now, (-6) will be the power...

The base was same, so we will take 1 out of them as common...

= (2/5)^-6

Hope it helps.

Answer 2

Answer:

first of all inverse these terms as it has negative exponents, then all are similar so common term will be written.

(5/2) power2 = 5×5/2×2=25/4

so answer is 25/4.
