Solution:
Given a number N in product of its prime factors.
Now, express as a product of prime factors in index form.
Substitute in place of N.
Use exponential rule:
Multiply the power 2 into the powers of factors of every number in the bracket.
Arrange like terms together.
Use exponential rule:
Hence .
Answer:
A. y + 1 = -2(x – 5)
Step-by-step explanation:
For a line with slope m through point (h, k), the equation is ...
y -k = m(x -h)
Fill in your values of m=-2, h=5, k=-1 and you have ...
y -(-1) = -2(x -5)
y +1 = -2(x -5) . . . . . . simplify. Matches selection A.
E.g.
4
4/4=1
but
4/8=0 remainder 4
--------------------------------
12
12/4=3
but
12/8=1 remainder 4
