Answer:


Step-by-step explanation:
is the expression given to be solved.
First of all let us have a look at <u>3 formulas</u>:

Both the formula can be applied to the expression(
) during the first step while solving it.
<u>Applying formula (1):</u>
Comparing the terms of
with 

So,
is reduced to 
<u>Applying formula (2):</u>
Comparing the terms of
with 

So,
is reduced to
.
So, the answers can be:


Answer:

Step-by-step explanation:
Multiplying 5 by itself is the same thing as raising it to the second power:

We multiply 2 by itself two seperate times. That's the same thing as raising 2 to the second power to the second power or in simpler terms raising two to the fourth power:

Since only multiplication is present, we can combine the two terms to get:

X=numbers of hammers
y=numbers of scewdrivers
f(x,y)= total cost in $
f(x,y)=11x+6.65y
f(4,7)=4(11)+6.65(7)=44+46.55=90.55
Sol: an expresion for the total cost of the tools is f(x,y)=11x+6.65 y;
x=number of hammers
y= number of scewdrivers.
The total cost is $90.55
