Question

Find the value of m:​

Answer 1

base are same therefore we have to calculate only exponents

according to exponent laws

6m-(m-5)=-12

= 6m -m +5 = - 12

= 5m+5 = -12

= 5m = -12-5

m = -17/5

$...$

Answer 2

Answer:

as the bases are same

power will be subtracted

6m-(m+5)= -12

6m-m-5= -12

4m-5=-12

4m= -7

m=-7/4
