Answer:
B
Lemme explain rq.
If a number has a fractional exponent, that bottom part of the fraction goes the to root side when it is turned into a root.
Step-by-step explanation:
For example, 4 to the power of 2/3 becomes cube root of 4 to the power of 2.
When an exponent to a number also has a power
For example:
4 to the power of 2 to the power of 3
So B because B is the only one where the two powers are multiplied.
Answer:
see below
Step-by-step explanation:
To find miles per hour, divide miles by hours:
(5 2/3 mi)/(2 2/3 h) = (17/3 mi)/(8/3 h) = (17/8) mi/h = 2 1/8 mi/h
Hours per mile is the reciprocal of that:
1/(17/8 mi/h) = 8/17 h/mi
If the given equation is
first simplify the left side using the fact that 27 = 3³:
and on the right side, 9 = 3²:
So we have
Next,
so that
and dividing both side by 3 gives
Isolate 3ˣ :
Solve for x by taking the base-3 logarithm of both sides:
