Step-by-step Solution
To simplify the expression \( \left(\frac{1.8}{1.6}\right)^{4} \) using the power of a quotient exponent law, we can apply the following rule:
\[
\left(\frac{a}{b}\right)^{n} = \frac{a^{n}}{b^{n}}
\]
In this case, \( a = 1.8 \), \( b = 1.6 \), and \( n = 4 \). Therefore, we can rewrite the expression as:
\[
\left(\frac{1.8}{1.6}\right)^{4} = \frac{(1.8)^{4}}{(1.6)^{4}}
\]
Now, we can calculate \( (1.8)^{4} \) and \( (1.6)^{4} \):
1. Calculate \( (1.8)^{4} \):
\[
(1.8)^{4} = 1.8 \times 1.8 \times 1.8 \times 1.8 = 10.4976
\]
2. Calculate \( (1.6)^{4} \):
\[
(1.6)^{4} = 1.6 \times 1.6 \times 1.6 \times 1.6 = 6.5536
\]
Now, substitute these values back into the fraction:
\[
\frac{(1.8)^{4}}{(1.6)^{4}} = \frac{10.4976}{6.5536}
\]
Now, perform the division:
\[
\frac{10.4976}{6.5536} \approx 1.60
\]
Thus, the simplified result of \( \left(\frac{1.8}{1.6}\right)^{4} \) is approximately \( 1.60 \).
Quick Answer
The simplified result is approximately \( 1.60 \).
