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.
Step-by-step explanation:
It is multiplication? If it is, the answer is 6/8. Simplified it is 3/4.
Answer:
10 m
Step-by-step explanation:
15m - 5m = 10 m
both numbers have m which are alike
5t=3b+660....and....2t+5B=450
from the first we can see that the t=(3b+650)/5 and using this value in the second.
(6+1320)/5+5b=450 making all have common denominator.
6b+1320+25b=2250
31b=930
b=30.. and 2t+5b=450
t=150
