Question

Which is an equivalent form of the expression 1800 (1.2) ^-t

Answer 1

Answer:

Option B will be the correct option.

Step-by-step explanation:

The given expression is $1800\times (1.2)^{-t}$

We can rewrite the term as

$1800\times (\frac{1}{1.2})^{t}$

[As we know $x^{-1}=\frac{1}{x}$]

Now we will simplify the expression

= $1800(\frac{10}{12})^{t}$

= $1800(\frac{5}{6})^{t}$

Therefore, Option B will be the correct option.
