Answer:
The answer is x=4 or x=−10
Solutions:
(x + 3)² = 49
(x+3)(x+3)=49
x²+6x+9=49
x²+6x+9-49=0
(x-4)(x+10)
x-4=0 x+10=0
x=4 x=-10

Answer:
To help in solving exponential equations when relating the bases cannot be used
Step-by-step explanation:
Recall an equation of the form
from the expression , is the base and the power is .
it is impossible to carryout the operation since the bases are not equal.
This is where we implore the help of logarithm which help us to bring the base to a come base i.e using the property below
.
Hence we can conclude that logarithm helps in solving equations when bases cannot easily be related.
