Answer:
The answer is 4
Step-by-step explanation:
{7 + 4 = 11} {11 times 3 = 33} {33 - 5 = 28} {28 divided by 4 = 7}
Then,
3^y = 7, is equivalent to y = log_3(7)
We need to find which graph goes like log_3(x). For x =3, log_3(3) = 1, for x = 9, lo_3(9)=2, so .....
The first one!
Answer:
Step-by-step explanation:
If you want to find out how many times larger something is than something else, you have to divide. We will set up a problem that looks like this:

Diving 2.1 by 4.2 gives us .5; to divide the exponents, we remember that if we divide like bases we have to subtract the exponents. 10 is our base in both cases, so 8 - 2 gives us 6, resulting in:

However, this isn't in scientific notation. We need to move the decimal one more place to the right, which in trn reduces the exponent by 1:
