Answer 2

Answer:

$5^{9}$

Step-by-step explanation:

Indicie multiplication works by adding the exponent presuming that the base is the same.

$4^{7}$, 4 is the base and so stays the same, 7 is the exponent.

$x^{2}$, here the equation is the same as x * x as exponents work by multiplying the base, x, by iteself y times, where y is the exponent and in this case 4.

As we know this, $x^{2} * x^{2}$ can be simplified too $x^{4}$, which is the same as

x * x * x * x, so we know in such a situation we just add the two exponents together.
