Step-by-Step Solution

In the first stage, let's calculate the powers of each of the terms:

53=5×5×5=25×5=125 5^3=5\times5\times5=25\times5=125

52=5×5=25 5^2=5\times5=25

23=2×2×2=4×2=8 2^3=2\times2\times2=4\times2=8

Now let's write the resulting expression:

125:25×8= 125:25\times8=

Since the only operations in the expression are multiplication and division, we will solve the expression from left to right

In other words, we will divide first and then multiply:

125:25=5 125:25=5

5×8=40 5\times8=40
