The bases were not the same when the exponents were set equal to each other.
16 should have been written as 4 squared.
The exponent on the right should be 4a instead of 8a.
The correct solution is a=-3/4.
Answer:
Step-by-step explanation:
We have to find the error in the given work.
Reason: Given
Using the property then we get
By the property ()
When bases are equal then power will be equal
Therefore,
But in given work bases are not same but he wrote power equal.
This is the error in given work.He wrote instead of
all inputs are equal to <u>3</u>
Answer: 15 and one-half
14/2 + 3(4) - (6.5 - 3)
Use PEMDAS
14/2 + 3(4) - 3.5
7 + 12 - 3.5
15.5
