Question

Which exponent makes this statement true? 1/5^9= 5^?

Answer 1

1/5^9 = 5^-9

Explanation:

Answer 2

The exponent -9 makes the given statement true.

Explanation:

We have been given an incomplete mathematical statement and we need to figure out the exponent for 5 on the right hand side to complete the statement.

The given incomplete statement is
`(1)/(5^(9))=5^(?)`.

Let us rewrite the left hand side of the expression by moving the exponential term to the numerator using exponent property. As per this property, if we shift an exponential term from denominator to numerator (or vice versa), the sign of exponent changes.

Therefore, we get:

`5^(-9)=5^(?)`

Now that we have common bases on both the sides, we can equate the exponents. And upon equating the exponents, we can see that the 'question mark' should be replaced by -9 in order for statement to be true.

Therefore, exponent -9 on the right hand side will make the statement true.
