Answer:
x=-8
Step-by-step explanation:
on squaring both sides
either x-2=0 or x+8=0
either x=2 or x=-8
Putting x=2 in original equation, we get
7=7 hence, it is not an extraneous solution
Putting x=-8 in original equation
i.e. 3=-3
Hence, x=-8 is an extraneous solution (since it doesn't satisfy the original equation)
The expression which is equal to the m times, m times, m times, m times, m rewritten in exponential form as,
The exponent or power of a number represent the multiplication of the that number to the power times.
Let suppose a number 2 has the power 2. Then it will be equal to,
Similarly, 3 times of number 2 equal to the number 2 with exponent 3.
The expression is m times, m times, m times, m times, m. It can be written as,
The number m is total 5 time multiply by itself. Thus, the exponential form of the above equation is,
The expression which is equal to the m times, m times, m times, m times, m rewritten in exponential form as,
