How do you solve 10(3^x) = 810 ?
Answers
3^x = 81
Since 81 has a perfect fourth power of 3, which is 3*3*3*3 = 3^4 = 81
3^x = 3^4
You can easily remove the similar bases (which is 3) and bring down the exponent.
x = 4

What is an Inequality Equation?
Inequalities are the mathematical expressions in which both sides are not equal. In inequality, unlike in equations, we compare two values. The equal sign in between is replaced by less than (or less than or equal to), greater than (or greater than or equal to), or not equal to sign.
In an inequality, the two expressions are not necessarily equal which is indicated by the symbols: >, <, ≤ or ≥.
Given data ,
Let the inequality relation be A
And the equation is 3x - 2 ≤ 2x + 1.
So , on simplifying the equation , we get
3x - 2 ≤ 2x + 1.
Subtracting 2x on both sides of the inequality equation , we get
x - 2 ≤ 1
Adding 2 on both sides of the inequality equation , we get
x ≤ 3
Therefore , the value of x satisfies all the numbers that are less than or equal to 3
Hence , The solution set is {x | x R, x ≤ 3}

xyz=(x)(y)(z)
if x and y and z are all perfect cubes, xyz is also a perfect cube
remmeber
(x^n)^m=x^(mn)
so if it is perfect cube it can be factored into
(x^n)^3, such taht n is a whole number
basiclaly, see if the expoent is divisble by 3
all of them should be perfect cubes
215x^18y^3z^21
split them up to see which ones need changing
215=5*43, not a perfect cube
could be changed to 6^3, which is 216
x^18=(x^6)^3
y^3=y^3
z^21=(z^7)^3
the 215 needs to be changed
