Question

plz help me out frends Tomorrow is my exams of maths​

Answer 1

Answer:

Step-by-step explanation:

$a) (-2)^m*(-2)^6 = (-2)^8\\(-2)^{m+6}= (-2)^8\\=> m+ 6= 8\\=>m= 8-6\\=> m = 2$

$b) (-6)^{-5}*(-6)^{-11}= (-6)^{8m}\\(-6)^{-5+-11} = (-6)^{8m} \\=> -16 = 8m\\=>m=-16/8\\=> m = -2$

$c) (4/5)^{6}*(4/5)^{-3} = (4/5)^{2m-3} \\(4/5)^{6-3}= (4/5)^{2m-3}\\=> 3 = 2m-3\\=> 3+3 = 2m\\=> m = 6/2\\=>m= 3$

$d) 6^{4} / 6^{9} = 6^{m+1}\\6^{4-9} = 6^{m+1}\\=> -5 = m+1\\=> m = -5-1\\=> m = -6$

$e) 9^{-4}*9^{6}= 9^{2m}\\9^{-4+6}= 9^{2m}\\=> 2= 2m\\=>m=2/2\\=>m=1$

Hope this helps!!!
