Answer:
see attached
Step-by-step explanation:
You want to use q=4 to show q×q³ = q⁴.
Exponents
The attachment shows your calculator can help with this. It will compute and display the powers of values without requiring the intermediate calculations.
4 × 4³ = 4 × 64 = 256
4⁴ = 256 . . . . . . equivalent to 4 × 4³
Repeated multiplication
An exponent signifies repeated multiplication in the same way a coefficient signifies repeated addition.
4 × 4³ = 4 × (4·4·4) = 4·4·4·4 . . . . . using the associative property of multiplication
4⁴ = 4·4·4·4 . . . . . . . equivalent to 4 × 4³

Additional comment
In literal terms, ...
q×q³ = q·q·q·q = q⁴
