Set this up as a proportion with seeds on top and plants on bottom. Ours will look like this:
. Cross multiply to get 12x=1092. Divide to get that the number of plants to expect from 156 seeds is 91, choice B from above.
Answer:
It depends on the equation.
If the bases are equal and the variables are only in the exponents, set the exponents equal.
If there are variables in the exponents, but you cannot set the bases equal, then use logarithms.
Example 1:
Here you have the same base on both sides. The variables are in the exponents. Set the exponents equal and solve for x.
2x + 5 = 9
2x = 4
x = 2
Example 2:
The bases are different, but you can make the bases equal using laws of exponents. Remember that 9 = 3^2.
Now you have equal bases, so the exponents must be equal.
2x = 12
x = 6
Example 3:
Here you can't make the bases equal, so you take the log of both sides and use laws of logs.
Recall that:
4096
(4^3)(4^4) = 4n
16384 = 4n
4n = 16384
4n/4 = 16384/4
n = 4096
