2•3^-4/5^-2 simplify
To simplify 2•3^-4/5^-2, we need to apply the rules of exponents.
The rule states that when you have a negative exponent on a number or variable, you can move it to the denominator by changing the sign of the exponent.
So, in this case, we can rewrite the expression as:
2 • (5^2/3^4)
Now, we can simplify the exponents by calculating the values:
2 • (25/81)
Finally, we multiply 2 by the fraction:
2 * 25/81 = 50/81
Therefore, 2•3^-4/5^-2 simplifies to 50/81.
