Answer:
5^16
Step-by-step explanation:
25^9 + 5^17
Replace 25 with 5^2
5^2^9 + 5^17
We know that a^b^c = a^(b*c)
5^(2*9)+ 5^17
5^18+ 5^17
We can factor out 5^17
5^17 (5+1)
5^17(6)
But we need 30 so I need one more 5 inside 5^17 = 5^16 *5
5^16 *5 *6
5^16(30)

Answer:
i think its 80.64 i don’t know if its correct
Step-by-step explanation:
To answer this, set up a system of equations. What we know is that
5x + 2y = 100
And...
x+y=38
x represents the unknown number of 5 points questions
y represents the unknown number of 2 point questions
In my opinion the easiest way to solve this is to use substitution (that is when you find out the value of one variable, either x or y, and substitute that value as the variable).
So,
x+y=38
Subtract x from both sides
y=38-x
Now, plug (38-x) in as y in the other equation.
5x + 2(38-x) = 100
5x + 76-2x= 100
3x+76=100
3x=24
x=8
Now that you know that x=8, you can solve for y.
5x+2y=100
5(8)+2y=100
40+2y=100
2y=60
---- ------
2 2
y=30
X=8
Y=30
There are 8 five point questions on the test and 30 two point questions on the test
