Solve for x. M=5/dx+e

snow_lady [41]

After solving $M=\frac{5}{dx}+e$ we get value of x: $x=\frac{5}{(M-e)d}$

Step-by-step explanation:

We need to solve the equation $M=\frac{5}{dx}+e$ to find value of x

Solving

$M=\frac{5}{dx}+e$

Adding -e on both sides

$M-e=\frac{5}{dx}+e-e$

$M-e=\frac{5}{dx}$

Multiply both sides by dx

$dx(M-e)=5$

Divide both sides by M-e

$dx=\frac{5}{M-e}$

Divide both sides by d

$x=\frac{5}{(M-e)d}$

So, After solving $M=\frac{5}{dx}+e$ we get value of x: $x=\frac{5}{(M-e)d}$

Rewrite the expression in the form 5^n<br> 5^10/5^12

weqwewe [10]

Answer:

Step-by-step explanation:

This problem is all about bases and exponents. Because we have a quotient and the bases are both 5's, that means that we can use the rule of exponents for quotients to rewrite and simplify:

$\frac{5^{10}}{5^{12}}=5^{10-12}=5^{-2}$
