Answer:

4y + yz

Step-by-step explanation:

the grouping symbols can be parentheses, brackets, or in this case a sign of multiplication ·

you have the expression

y · 4 +y ·z

to eliminate the symbol  · from the first term you just do the multiplications:

y multiplied by 4 is equal to 4y

and to eliminate the symbol  · from the second term, since we don't know the values to y and z, we let them indicates as yz, because the simple fact of two variables written together is indication of a multiplication.

So the result is:

4y + yz

amid [387]

Answer:

Step-by-step explanation:

An index number is a number which is raised to a power. The power, also known as the index, tells you how many times you have to multiply the number by itself. For example, 2^5 means that you have to multiply 2 by itself five times = 2×2×2×2×2 = 32. There are a number of important rules of index numbers: y^a × y^b = y.
