Answer:
The value of a = 7, or the value of a = -7
Step-by-step explanation:
Here, the given expression is : [tex]3a^{2} = 147[/tex]
Now, we need to simplify for the value of a.
Solving the above equation, we get
[tex]3a^{2} = 147[/tex]
⇒[tex]a^{2} =\frac{147}{3} = 49[/tex]
or, [tex]a^{2} = 49[/tex]
⇒ [tex]a = \sqrt{49} [/tex]
⇒ a = + 7, or a = -7
Hence, the value of a = 7, or the value of a = -7
