Answer:
1/60466176
Step-by-step explanation:
Given: (6^2)^4 ÷ 6^18
Parentheses: 36^4 ÷ 6^18
36^4 ÷ 36^9 (Because 6^18=6^2^9=36^9)
36^-5 (Exponents get subtracted)
1/(36^5)
1/60466176
Another way:
(6^2)^4 ÷ 6^18
6^(2*4) ÷ 6^18
6^8 ÷ 6^18
6^(8-18)
6^-10
1/(6^10)
1/60466176
Solve for x:(2 x + 3)/3 - 1 = 10
Put each term in (2 x + 3)/3 - 1 over the common denominator 3: (2 x + 3)/3 - 1 = (2 x + 3)/3 - (3)/3:(2 x + 3)/3 - (3)/3 = 10
(2 x + 3)/3 - (3)/3 = ((2 x + 3) - 3)/3:(-3 + 3 + 2 x)/3 = 10
Add like terms. 3 - 3 = 0:(2 x)/3 = 10
Multiply both sides of (2 x)/3 = 10 by 3/2:(3×2 x)/(2×3) = (3×10)/2
(3×10)/2 = (3×10)/2:(3×2 x)/(2×3) = (3×10)/2
(3×2 x)/(2×3) = (2×3)/(2×3)×x = x:x = (3×10)/2
10/2 = (2×5)/2 = 5:x = 3×5
3×5 = 15:Answer: x = 15
