Question

(a) Find the value of m for which 5raise to power m – 5 raise to power -3 =5 raised to power3​

Answer 1

Answer:

5^m - 5 ^-3 = 5 ^3

the powers are equal (law)

m -(-3) = 3

m + 3 = 3

m= 3-3

m=0 answer

hope it helps

Answer 2

Answer:

Step-by-step explanation:

IT IS SAID THAT,

5^m -5^(-3) = 5^3

SO, THE NUMBER ON WHICH POWER IS BEING TAKEN IS SAME IN EVERY CASE. SO WE CAN SIMPLY TAKE THE POWERS TO FIND THE ANSWER.

SO,

m - (-3) = 3

m + 3 = 3 ______________( AS - * - IS

EQUAL TO+)

m = 3 - 3 ______________( WHEN A

NUMBER IS

TRANSFERED

TO THE

OTHER SIDE

OF = ITS VALUE

CHANGES)

THEREFORE, m = 0
