What is a rule for the sequence 1.8, 2.85, 3.90, 4.95, 6

1 answer:

7 0

The rule is add 1.05 because it's 1.8 first then it's 2.85 so you add 1.05 to 1.8 and you will get 2.85. Same with the other numbers.

Hello there. May somebody help me simplify this problem? It would be very kind.

marissa [1.9K]

Answer:

27 / (4x⁶y⁸)

Step-by-step explanation:

$\frac{4(3x^{2}y^{4})^{3}}{(2x^{3}y^{5})^{4}}$

When raised to a power, multiply the exponents.

$\frac{4(3^{3}x^{6}y^{12})}{2^{4}x^{12}y^{20}} \\\\\frac{2^{2}3^{3}x^{6}y^{12}}{2^{4}x^{12}y^{20}}$

When dividing, subtract the exponents.

$2^{2-4}3^{3}x^{6-12}y^{12-20}\\2^{-2}3^{3}x^{-6}y^{-8}$

Move negative exponents to the denominator.

$\frac{3^{3}}{2^{2}x^{6}y^{8}}\\\frac{27}{4x^{6}y^{8}}$
