4 & 3
step-by-step explanation:
factor of 108=2×2×3×3×3=2×2×3^3=the number is 4 because 2 only occurs 2 times and 2×2=4 and factor of 2187=3^3×3^3×3=the number is 3 because 3 onlyvoccur 1 time.
x > 1.3
step by step:
8.5−0.9x> 9.8−1.9x
step 1: simplify both sides of the inequality.
−0.9x+8.5> −1.9x+9.8
step 2: add 1.9x to both sides.
−0.9x+8.5+1.9x> −1.9x+9.8+1.9x
1x+8.5> 9.8
step 3: subtract 8.5 from both sides.
1x+8.5−8.5> 9.8−8.5
1x> 1.3
step 4: divide both sides by 1.
1x/1 > 1.3/1
