Solve the equation.

[tex]\[ 6 + \sqrt[4]{m} = 8 \][/tex]

Select one:
a. [tex]\(\{16\}\)[/tex]
b. [tex]\(\{4\}\)[/tex]
c. [tex]\(\{\pm 16\}\)[/tex]
d. [tex]\(\{\pm 4\}\)[/tex]

Sagot :

Certainly! Let's solve the equation step by step:

1. We start with the given equation:
[tex]\[ 6 + \sqrt[4]{m} = 8 \][/tex]

2. To isolate the term involving [tex]\( m \)[/tex], we subtract 6 from both sides of the equation:
[tex]\[ \sqrt[4]{m} = 8 - 6 \][/tex]
Simplifying the right-hand side, we get:
[tex]\[ \sqrt[4]{m} = 2 \][/tex]

3. Next, we need to eliminate the fourth root by raising both sides of the equation to the power of 4:
[tex]\[ (\sqrt[4]{m})^4 = 2^4 \][/tex]
On the left-hand side, raising the fourth root of [tex]\( m \)[/tex] to the power of 4 simply leaves us with [tex]\( m \)[/tex]:
[tex]\[ m = 2^4 \][/tex]

4. Now calculate [tex]\( 2^4 \)[/tex]:
[tex]\[ 2^4 = 16 \][/tex]

Therefore, the solution to the equation is:
[tex]\[ m = 16 \][/tex]

So the correct answer is:
a. [tex]\(\{16\}\)[/tex]
