Question

Find the value of m ,if (-5)^m+1×(-5)^6=(-1)^9 (5)9​

Answer 1

75

Step-by-step explanation:

-5*m + -30=-9*45

-5*m=-405+30

m=-375/-5=75

Answer 2

Answer:

m= 2

Step-by-step explanation:[ -5^]m+1 multiply [-5]^6 =[ -1]^9[ 5]9

1. -5^m+1 × -5^6 =[ -1 ×5]^9 as                                        
2. -5^m+1+6 = -5^9
3. when cofficent are same power get equall
4. m+1+6=9
5. m+7=9
6. m=2
