Alice, beth, and charlene start climbing a staircase, each with her left foot on step 1 and then her right foot on the next step they take. alice climbs one step at a time, beth 2 steps at a time, and charlene 3 steps at a time. each lands on the top step with her left foot. what is the minimum number of steps in the staircase?

That is basically the the LCM of 1,2, and 3 or the lowest number that is divisible by 1, 2, and 3.

That would be... 1x2x3 = 6 steps

6 steps

the answer is:

the correct option:

b.

to solve the problem, we need to remember how to operate to simplify exponential expressions using the logarithms.

we are given the equation:

then, using placing logarith with base 7 on both sides of the equation, we have:

so, rounding the obtained result to two decimal places (nearest hundreth), we have:

hence, we have that the correct option:

b.

have a nice day!
