I believe it is 100 because 462-367=100 so I believe it would be 100
We have to simplify the expression here. The expression given,

Now to find
we will use power of a product property. We have to distribute the power here. We will get,

= 
Now we will use power of a power property. If given
we will have to multtiply the powers and we will get
. So we will get here,

Now the next part is 
By using power of a power property we will get,

Now we have to multiply them.

Now we have to use product of powers property. If we have same base them we will have to add the exponents there. The formula is
. So we will get here,


So we have got the required simplified answer here.
The simplified answer is
.
Answer:
Step-by-step explanation:
Answer:
Mikhail is 5 years old
Step-by-step explanation:
Represent each member with a variable.
X= Gabrille
Y=Mikhail
X+Y=20 (sum of their ages is 20)
X=3y (Gabrille is 3 times Mikhails age)
Substitute 3Y into the first equation (simultaneous equation)
. 3y+y=20
. 4y=20 (divide both sides by 4)
y=5
To check your answer.
X+5=20
X=20-5
X=15
15 is 5 times 3.
