If 36^12-m=6^2m what is the value of m??
skad [1K]

Answer:

m=6

Step-by-step explanation:

if 36^12-m=6^2m , find the value of m

36^{12-m}=6^{2m}

To make the exponents equal , we need to get the same base.

The base of both sides of equation are not same.

36 can be written as 6^2

6^{2(12-m)}=6^{2m}

6^{24-2m}=6^{2m}

now base of both sides are same . so we equate the exponents

24-2m= 2m

add 2m on both sides

24=4m

divide by 4 on both sides

6=m

The value of m is 6
