Title: Solve the equation

Grade: 7-b Lesson: S2-L9

Explanation: Hello Students, time to practice and review the steps for the problem.

Lesson Steps

Steps	Problem	Solution
1	Solve	\$ 5n^3 + 6 = 16 \$
2	Move constant term to the right side	\$ 5n^3 = 16 - 6 \$
3	After Subtraction	\$ 5n^3 = 10 \$
4	Dividing on both sides by '\$ 5\$' of the equality	\$ \cancel(5)^1/ \cancel(5)^1 n^3 = \cancel(10)^2/ \cancel(5)^1 \$
5	After cancelation	\$ n^3 = 2 \$
6	Applying cube root on both sides	\$ root3(n^3) = root3(2) \$
7	After Simplification	\$ n = 2\sqrt2 \$
8	Answer	A = \$ n = 2\sqrt2 \$

Steps

Problem

Solution

Solve

\$ 5n^3 + 6 = 16 \$

Move constant term to the right side

\$ 5n^3 = 16 - 6 \$

After Subtraction

\$ 5n^3 = 10 \$

Dividing on both sides by '\$ 5\$' of the equality

\$ \cancel(5)^1/ \cancel(5)^1 n^3 = \cancel(10)^2/ \cancel(5)^1 \$

After cancelation

\$ n^3 = 2 \$

Applying cube root on both sides

\$ root3(n^3) = root3(2) \$

After Simplification

\$ n = 2\sqrt2 \$

Answer

A = \$ n = 2\sqrt2 \$
