Question

How do I solve 1.5 to the -2 power or 1.5^-2 (its an exponent) I have had to repost this like 3 times IF YOU ARE NOT SURE THEN DONT ANSWER the answer is .4 repeating if your explanation does not get that move along

Answer 1

see explanation

Explanation:

Using the rule of exponents

`a^(-m)` ⇔
`(1)/(a^(m) )` , then

`1.5^(-2)`

=
`(1)/(1.5^(2) )`

=
`(1)/(2.25)`

= 0.4444.....
