Answer: 25

Step-by-step explanation:

Plug in x to the expression.

So this simplifies to, 5^2.

This then solves to 25.

Answer:

98 x 3 = 294 or 3 x 98 = 294

Step-by-step explanation:

Since 294 divided by 3 is 98, that means 294 is 3 times 98. So, we can say:

In the equation (m^5/6) (m^1/6)^7 = m^x , what is the value of x that makes the equation true?
vlabodo [156]

{m}^{ \frac{5}{6} }  \times (m {}^{ \frac{1}{6} } ) {}^{7 }  = m {}^{x}

m {}^{ \frac{5}{6} }  \times m {}^{ \frac{7}{6} }  = m {}^{x}

{m}^{ \frac{5 \times 7}{6 \times 6} }  =  {m}^{x}

\frac{35}{36}  = x
