㏑(8^2) = ㏑(64)
or
㏑(a^n) = n㏑(a)
so
2㏑(8) = ㏑(64)
Is it what you mean by logarithmic equation ?
Answer:
x = 28/3
y = 7/3
Step-by-step explanation:
If the triangles are congruent, then corresponding sides are equal.
x = 4y
x + 1 = y + 8
Solve the system of equations using substitution or elimination. Using substitution:
4y + 1 = y + 8
3y = 7
y = 7/3
Solving for x:
x = 28/3
Answer:
7507
Step-by-step explanation:
8760-1253=7507
You can then write really big numbers without running out of space
for example instead of 2300000000000000000000000000
you can just write 2.3 x 10^27
Answer:
B. 6Fx + 6Gy = 6H
Qx + Ry = S
Step-by-step explanation:
Equivalent equations can be created many ways. One of the simplest is to multiply both sides of the equation by the same number. In the answer above, the first equation has been multiplied by 6. Nothing has been done to the second equation.
_____
<em>Comments on other choices</em>
A: some terms have been multiplied by 6. This changes the equation(s) so they are no longer equivalent to the ones you started with.
B: the correct choice
C: see A.
D: the first equation has been multiplied by 6, so that is equivalent to the original. The second equation has the sign of one of the terms changed, so it is now a different equation.
