90^6=531441000000
80^-4= 1/80^4= 1/4960000
For this, use negative power rule x^-a= 1/x^a
Answer:x=150
Step-by-step explanation:
Step 1: Subtract 1.2x from both sides.
0.8x+20−1.2x=1.2x−40−1.2x
−0.4x+20=−40
Step 2: Subtract 20 from both sides.
−0.4x+20−20=−40−20
−0.4x=−60
Step 3: Divide both sides by -0.4.
−0.4x
−0.4
=
−60
−0.4
