When you are multiplying 2 numbers with exponents, you need to add the exponent. When you multiply an exponent with an exponent, you multiply them.
So,
(3^2 x 7^4) ^9
First multiply the base and add exponents = ( 21^6) ^9
= 21 ^6x9
21^54
The same rule applies for variables, just pretend there is an imaginary 1.
Answer:
2x+2y=8
Step-by-step explanation:
Answer:
Step-by-step explanation:
any point looks like this --> point A = ( x, y )
point 1 = (5,4)
point 2 = (-9, 2)
we are given these points and are asked what is the x coordinate that is in the middle
so find the distance between the two 'x' coordinates
5 - (-9)
5 + 9 = 14
that's the distance between the points , now chop that in half. so 7
now add 7 to negative 9
or subtract 7 from 5
either way gets -2
-2 is the mid point of the 'x' coordinate
Answer:
x=7
Step-by-step explanation:
have a great day :D
The two numbers are 18 and 8. 18+8=26 and when you subtract them, 18-8=10.
