Question

evaluate 5+2k² when k=4.

Answer 1

first we do exponents (following PEMDAS). if k is 4, than 4 times 4 is 16. next multiply 2 times 16 which is 32. then 32 plus 5 is 37. hope this helps!

Answer 2

$\huge\text{Hey there!}$

$\huge\boxed{\mathsf{5 + 2k^2}}\\\\\huge\boxed{\mathsf{\rightarrow 5 + 2(4)^2}}\\\\\huge\boxed{\mathsf{\rightarrow 5 + 2(\bf 4\times4)}}\\\\\huge\boxed{\mathsf{\rightarrow 5 + 2(\bf 16)}}\\\\\huge\boxed{\mathsf{\rightarrow 5 + \bf 32}}\\\\\huge\boxed{\mathsf{\rightarrow \bf 37}}\\\\\\\huge\text{Therefore, your answer is: \boxed{\textsf{37}}}\huge\checkmark$
