Question

4) Find the value of m. if (-3)m+1 x (-3)-3 = (-3)7​

Answer 1

Answer:

$( - 3)m + 1 \times ( - 3)( - 3) = ( - 3)7 \\ ( - 3m + 1)9 = ( - 21) \\ - 27m + 9 = ( - 21) \\ - 27m = - 21 - 9 \\ - 27m = - 30 \\ m = \frac{ - 30}{ - 27} = \frac{10}{9}$

The value of m is 10/9.

Answer 2

Step-by-step explanation:

(−3)m+1×(−3)(−3)=(−3)7

(−3m+1)9=(−21)

−27m+9=(−21)

−27m=−21−9

−27m=−30

m= -30

-27

m=10

9
