Answer:
4√2 × 4√8 = 64, an integer.
Step-by-step explanation:
a) 4√2 × 4√8
First let's remember that a square root can be rewritten as a 1/2 exponent,
Therefore the expression we have can be rewritten as

We are going to write all numbers in their prime factor expressions:
<u>*Note: Remember that when we multiply two numbers with the same base but different exponents we sum up the exponents*</u>
<u>*Also, when we elevate one exponent to another exponent, we multiply the exponents*</u>

Therefore, the expression 4√2 × 4√8 = 64 and therefore is an integer
49.9 x 9+6=456////
Hope this helps.
Answer:
Step-by-step explanation:
Steps Property
x(1 + y) + y(2 + x) Given
x + xy + 2y + xy Distributive property
x + xy + xy + 2y Commutative property of addition
[a + b = b + a]
x + (xy + xy) + 2y Associative property of addition
[(a + b) + c = a + (b + c)]
x + 2xy + 2y Combine like terms
X=number of the chairs y=the total cost of chairs
150/50=3$ y=3x
