Question

2. Find m so that (-3)" (-3)5 = (-3)​

Answer 1

Answer:

(−3)

m+1

×(−3)

5

=(−3)

7

(−3)

m+1+5

=(−3)

7

(−3)

m+6

=(−3)

7

On both the sides powers have the same base different from 1 and -1, so their exponents must be equal.

Therefore, m + 6 = 7

or m = 7 - 6 = 1

Step-by-step explanation:

(−3)

m+1
