Let's evaulate the given expression below:
[tex]\text{ 64}^2\text{ x 4}[/tex]Pressuming that this is the correct expression given, applying the PEMDAS Rule, let's first expand the number under exponential form before multiplying with a number.
We get,
[tex]\text{ 64}^2\text{ x 4 }\rightarrow\text{ 4,096 x 4 = 19,624}[/tex]Therefore, the product of the two number is 19,624.
