How to convert decimal to binary by hand?
Katena32 [7]
You have to divide decimal number by 2 and then to write the reminder. Then you have to continue to divide the result by 2 and so on. At the end you have to read all those reminders ( numbers 0 and 1 ) backwards and you will get the binary number. Example: Convert 10 ( decimal ) to binary.
10 : 2 = 5  |   0
  5 : 2 = 2  |   1
  2 : 2 = 1  |   0
  1 : 2 = 0  |   1
                        ↑
Finally:  10 ( decimal ) = 1010 ( binary )

Fully simplify using only positive exponents.
Assoli18 [71]

Answer:

\frac{xy^{3}}{25}

Step-by-step explanation:

Given

\frac{5x^6y^6}{125x^5y^3}

Required

Simplify the given expression

\frac{5x^6y^6}{125x^5y^3}

Start by applying law of indices

\frac{5x^{6-5}y^{6-3}}{125}

\frac{5xy^{3}}{125}

Divide numerator and denominator by 5

\frac{xy^{3}}{25}

Hence; the expression is equivalent to \frac{xy^{3}}{25}
