Take the cube root of both the left and right sides. What times what times what equals 125? What times what times what equals 27? Same with the x. x * x * x= x^3 because when multiplying x, we add the exponents. 5 * 5 * 5= 125. 3 * 3 * 3= 27.

x^3= 125/27
x= 5/3 or 1.6666667

Hope this helps! :)

Please express exponentiation with "^":  Solve x^3 = 125 / 27.

Find the cube root of both sides.  The cube root of x^3 is just x.
The cube root of 125 is 5, and the cube root of 27 is 3.  What is the value of x?

Write the first five terms of the sequence in which the nth term is a_n=(n+1)!/n+1.
VikaD [51]

Answer:a) 1,2,6,24,120

Step-by-step explanation:

The formula for the nth term of the sequence is expressed as

n=(n+1)!/n+1

For the first term, n = 1. Therefore,

(1+1)!/(1+1) = 2!/2 = (2×1)/2 = 1

For the second tern, n = 2. Therefore,

(2+1)!/2+1 = 3! /3 = (3×2×1)/3 = 6/3 = 2

For the third term, n = 3, therefore

(3+1)!/3+1 = 4!/4 =(4×3×2×1)/4 = 6

For the fourth term, n = 4. Therefore

(4+1)!/4+1 = 5!/5 = (5×4×3×2×1)/5 = 24

For the fifth term, n = 5. Therefore

(5+1)!/5+1 = 6!/6 = 6× 5×4×3×2×1)/6 = 120
