Answer:
The value of m is 1.
Step-by-step explanation:
Given : Expression (-3)^{m+1}\times (-3)^5=(-3)^7(−3)
m+1
×(−3)
5
=(−3)
7
To find : The value of m?
Solution :
Expression (-3)^{m+1}\times (-3)^5=(-3)^7(−3)
m+1
×(−3)
5
=(−3)
7
We know, x^a\times x^b=x^{a+b}x
a
×x
b
=x
a+b
(-3)^{m+1+5}=(-3)^7(−3)
m+1+5
=(−3)
7
(-3)^{m+6}=(-3)^7(−3)
m+6
=(−3)
7
Comparing the power as bases are same,
m+6=7m+6=7
m=1m=1
Therefore, The value of m is 1.

Answer:
The answer of m is minus 4
(minus3)m+1×(-3)6=(-3)10
-3m-18= -30
-3m= -30+18
-3m= 12
m= -4
