Answer:
6
Step-by-step explanation:
you kna mean?
For this case we must indicate the value of the following expression, expressed in scientific notation:
We have that for multiplication properties of powers of the same base, the same base is placed and the exponents are added:
Then, rewriting the expression we have:
Answer:
That means f(x)=kx²
so
f(5)=75=5²k
solve for k
75=5²k
75=25k
divide by 25
3=k
f(x)=3x² is da equation
so
f(4)=3(4)²
f(4)=3(16)
f(4)=48
