For alln∈N≥1(son≥1), and usingweakinduction, prove that:n∑i=1i3=[n(n+ 1)2]2Note that this result means that the sum of the third powers of the first strictly positive integers is equal to the sum of the same integers, squared=

Step-by-step explanation:

hello,

the question is not really clear. i believe the intended equation would be

please check the attached file for the step by step proof.

logv3(x+2)=1

rewrite in exponential form:

logb(x) = y is equal to b^y =x

b = 3, y = 1

now solve for x:

3^1 = x+2)

x = 3-2

x = 1

see the picture for the graph.

i use my brain for prombles like this maybe you could try it
