Question

Evaluate the expression. $$x^{6}-1 \text { when } x=1.2$$

Short answer

The evaluation of the expression \(x^{6} - 1\) when \(x = 1.2\) is approximately 1.985984

Step-by-step solution

Substitute the value of x

The value of \(x\) is given as 1.2. Substitute \(x = 1.2\) in the expression \(x^6 - 1\). After substitution we get \(1.2^6 - 1\).

Compute the expression

Now we want to compute the value of the expression \(1.2^6 - 1\). Using a calculator, \(1.2^6\) is approximately 2.985984. Subtract 1 from this number to get approximately 1.985984.
